Ford Engines: Common Problems and Key Specs

Ford has changed the way the automotive industry works a lot of times in its life. Every new engine from this company is certainly the technology to admire. Sometimes, the new technologies offered by Ford completely change the way we see cars.

In this article, I want to tell you briefly about each and every Ford engine that I have reviewed in this blog. This will be the huge list of engines with the basic information about them including some key specs and features and also the most common problems.

I will also update this page once I review another Ford engine. I hope this will be useful for you!

Ford 5.0L V8 Coyote engine

This is a huge part of the Modular Engine family made by Ford. It was introduced in 2011 and was full of all kinds of technologies that are now considered standard for big engines.

Ford used a very tricky Ti-VCT system for the first time in the V8 engine. Ford needed something to compete with Hemi and LS engines by its competitors and installed in the Mustang GT. Eventually, the Coyote engine powered the Mustang, the F-150, and other Ford vehicles.

This is a high-performance engine and its specs were adjusted for every kind of use. But one thing should be noted - the engine is not cheap to own and drive. Cam phaser issues have been reported largely.

Key features and my opinion:

• Production years:2011-now
• Average lifespan of Coyote:280,000-310,000 miles
• Fuel supply type:port injection, later-combined injection (port+direct)
• Power range:360-460 hp
• Fuel efficiency:awful
• Engine block material:aluminum
• Engine reliability score:high
• The most common problems:oil leaks, weak plugs and coils, electronic throttle issues, EGR problems.

Ford 9.0 EcoTorq engine

This is a commercial Ford engine built in Turkey and used mainly for commercial vehicles all over the world. This is the 9-liter straight-six diesel engine with OHV or OHC valvetrain type.

The engine is mainly used for different Ford trucks, Otosan vehicles in Turkey, KrAZ heavy-duty vehicles in Ukraine, and also JMC models in China. This is a very simple and reliable engine with enough power and torque to do almost anything in this world that an engine should be able to do.

The engine is turbocharged and can be used in several power and torque options. The main thing that changes from one modification to another is mapping and the turbocharger type. But even the most powerful versions are extremely reliable.

Key features and my opinion:

• Production years:2003-now
• Average lifespan of 9.0 EcoTorq:350,000-500,000 miles
• Fuel supply type:Common Rail
• Power range:240-500 hp
• Fuel efficiency:awful
• Engine block material:cast-iron
• Engine reliability score:high
• The most common problems:huge fuel consumption, diesel injection problems, oil leaks, vibrations and noise.

Ford 5.8L V8 Trinity engine

The Trinity engine or the 5.8L V8 powerplant is the special version of the Modular engine family made in 2013 for the limited Shelby edition of the GT500. This was the monster engine with a supercharger that could easily beat almost any other competitor on the market in terms of power and quality.

A lot of parts of this engine are Ford GT parts and some are taken from the Coyote like piston oil jets to lubricate and cool the engine when driving. The Eaton supercharger is probably not the most efficient thing, so there is room for upgrading.

Even in stock parameters, this engine could deliver 631 lb-ft of torque which is abnormally huge. Unfortunately, in 2014 it was discontinued.

Key features and my opinion:

• Production years:2013-2014
• Average lifespan of V8 Trinity:220,000-270,000 miles
• Fuel supply type:port injection
• Power range:671 hp
• Fuel efficiency:awful
• Engine block material:aluminum
• Engine reliability score:high
• The most common problems:piston wear problem, oil and coolant leaks, issue with supercharger.

Ford 5.2L V8 Voodoo engine

The Voodoo engine is the developed and upgraded Coyote with a little bigger displacement. It was specifically developed for the Ford Mustang Shelby GT model and wasn't used in any other vehicle.

Like other high-performance engines, the Voodoo engine is hand-built in one of Ford's plants in the US. There was also the GT350R version with the modification to the timing chain, VCT, and other mechanisms for even higher performance.

Even after being boosted so much, the V8 Modular engine remained very reliable. It will drink all the possible fuel that you can buy but it won't ask for expensive repairs for a very long time.

Key features and my opinion:

• Production years:2015-2020
• Average lifespan of V8 Voodoo:250,000-290,000 miles
• Fuel supply type:port injection
• Power range:526 hp
• Fuel efficiency:awful
• Engine block material:aluminum
• Engine reliability score:high
• The most common problems:overheating, ticking noises, oil consumption, weak timing chain tensioners.

Ford 5.2L V8 Predator engine

The 5.2L Predator engine was also engineered based on the Coyote powerplant. This is the V8 engine that was engineered for the Mustang Shelby GT500 and the F-150 Raptor R.

The high-performance unit is equipped with a supercharger which allows it to show perfect power and torque. The durability is affected by the boosting of power but still, this engine is capable of going a lot of miles and years with zero problems.

Actually, Ford stopped making the Predator engine in 2022 along with discontinuing the Shelby GT500 car forever.

Key features and my opinion:

• Production years:2020-2022
• Average lifespan of V8 Predator:230,000-260,000 miles
• Fuel supply type:port injection
• Power range:700-760 hp
• Fuel efficiency:awful
• Engine block material:aluminum
• Engine reliability score:medium
• The most common problems:overheating, oil consumption, weak timing chain tensioners, weak piston rings.

Ford 5.2L V8 Aluminator engine

This is the sibling of the Voodoo engine which is also based on the Coyote technologies. This engine has a different intake manifold called Cobra Jet. Also, it uses another type of the throttle body.

Interestingly, this engine hasn't been installed in any production cars made by Ford. This is the performance-oriented crate engine that you can buy and install in your truck or sports car.

Usually, people choose the Aluminator engine for Mustang or F-150 vehicles and it fits perfectly under the hoods of these models. But the engine is not huge, so it can be installed in many other car models.

Key features and my opinion:

• Production years:2010-now
• Average lifespan of V8 Aluminator:230,000-260,000 miles
• Fuel supply type:port injection
• Power range:580 hp
• Fuel efficiency:awful
• Engine block material:aluminum
• Engine reliability score:medium
• The most common problems:overheating, oil consumption, weak timing chain tensioners, weak piston rings.

Ford 5.2L V8 Carnivore engine

This engine is absolutely the same as the Predator but it uses a different supercharger for proper torque at the low RPM level. This makes the engine perfect for the Ford F-150 Raptor R. It can make the work of the truck engine and also deliver a lot of fun when driving.

Other than that, this is totally the Predator engine without any other differences.

Key features and my opinion:

• Production years:2020-2022
• Average lifespan of V8 Carnivore:230,000-260,000 miles
• Fuel supply type:port injection
• Power range:700 hp
• Fuel efficiency:awful
• Engine block material:aluminum
• Engine reliability score:medium
• The most common problems:overheating, oil consumption, weak timing chain tensioners, weak piston rings.

Ford 5.4 Triton engine

This is the part of the Modular engine - just like the V10 6.8L one but without two addition cylinders. There were versions with 2 valves per cylinder, 3 valves, and also 4 valves. The first ever 5.4L was introduced in 1997.

This is the V8 powerplant that was mainly used in trucks and vans but it also found its way to several SUVs. The last general version was made in 2014. But Branham tuned this engine for the BT62 model and it's still in production solely for this project.

There were issues with timing chains in all generations. Also, a lot of issues were reported for losing power. More than one owner reported ticking noise that was hard to diagnose and repair. VCT solenoids are also not perfect in the last generation of these engines.

Key features and my opinion:

• Production years:1997-2014
• Average lifespan of 5.4 Triton:300,000-340,000 miles
• Fuel supply type:port injection
• Power range:235-691 hp
• Fuel efficiency:bad
• Engine block material:cast iron
• Engine reliability score:high
• The most common problems:timing chain issues, mysterious ticking noise, oil consumption.

Ford 6.8L V10 Triton engine

The Modular engine family has the largest V10 gasoline engine with a 6.8L displacement. This is a lot but the 10-cylinder block makes each cylinder pretty small.

One of the interesting things is that the engine is built with SOHC technology (single overhead camshaft). This is actually the 5.4L engine but with two additional cylinders. There is a balance shaft in the block for smooth work. Because of the balance shaft, there is no variable valve timing.

The first-gen engine had 2 valves per cylinder while the second-gen got 3 valves per cylinder. Overall, the engine was used only in large trucks like the F250-F550, the Excursion, and the E-series vehicles. Of course, the fuel economy is non-existent here.

Key features and my opinion:

• Production years:1997-2019
• Average lifespan of V10 Triton:350,000-500,000 miles
• Fuel supply type:port injection
• Power range:288-362 hp
• Fuel efficiency:awful
• Engine block material:cast-iron
• Engine reliability score:high
• The most common problems:exhaust issues, spark plugs dying too soon, enormous fuel consumption, fuel pump issues.

Ford 6.2L Boss engine

The Boss engine, also called the Hurricane engine, is the 6.2L V8 powerplant introduced in 2010 for large trucks and commercial vehicles. Also, it was used in the F-150 Raptor in its early years.

The engine is pretty simple, naturally aspirated, with simple injection. It offers limited power in most models due to the priority of its torque. The powerplant is super reliable and you can easily use it as a substitution for an older Modular engine that has died because of its age or mileage.

In 2022, this unit was substituted by the Godzilla engine, so now it's only available used. But this is the legend of the Ford Company.

Key features and my opinion:

• Production years:2010-2022
• Average lifespan of Boss:350,000-400,000 miles
• Fuel supply type:port injection
• Power range:385-500 hp
• Fuel efficiency:awful
• Engine block material:cast-iron
• Engine reliability score:high
• The most common problems:heavy oil consumption, water pump problem, complicated spark plug replacement, enormous fuel consumption.

Ford 3.7L V6 Duratec engine

This engine is also called Duratec 37 and is part of the Ford Cyclone engines. The V6 engine was initially made to be installed in expensive premium vehicles of the company but eventually, it was widely used in different car models.

The engine is not that simple in terms of technology. It has a chain in its timing system and camshafts are equipped with phasers. The type of phasers may differ from one engine to another. The Duratec models aren't equipped with turbochargers but they are the base for the turbocharged EcoBoost engines.

Interestingly, this engine was used for the Mustang V6 2015.

Some early models were affected by the water pump issues which could destroy the engine once it happened.

Key features and my opinion:

• Production years:2009-2020
• Average lifespan of 3.7L V6 Duratec:210,000-250,000 miles
• Fuel supply type:port injection
• Power range:272-350 hp
• Fuel efficiency:bad
• Engine block material:aluminum
• Engine reliability score:medium
• The most common problems:water pump failure, phasers are pretty weak, oil leaks are common.

Ford 3.5L V6 Duratec engine

The Duratec 35 engine belongs to the same family as the Duratec 37 - the Cyclone engine family. It's also one of the legendary Ford engines introduced in 2007 to tackle the crisis.

In 2011 the engine went through a serious update and got the twin independent cam phasers instead of only one phaser on the intake camshaft. This made the engine even more efficient.

The engine was used in a ton of Ford vehicles and also in Lincoln, Mercury, and even Mazda cars. But it also had serious problems with the chain-driven water pump that could fail at about 100,000 miles and eventually kill the engine by overheating it to the temperature point of the hell.

Key features and my opinion:

• Production years:2007-2019
• Average lifespan of 3.5L V6 Duratec:210,000-250,000 miles
• Fuel supply type:port injection
• Power range:262-290 hp
• Fuel efficiency:bad
• Engine block material:aluminum
• Engine reliability score:medium
• The most common problems:water pump failure, phasers are pretty weak, oil leaks are common.

Ford 3.3L V6 Duratec engine

The last Cyclone family engine to mention here is the Duratec 33 introduced in 2018 as one of the reincarnations of the older engine types in this family.

So, this is basically the downsized Duratec 35 that shares all the technologies and also problems with its predecessor. Interestingly, it offers direct injection instead of the port one and this makes it way more interesting in terms of fuel efficiency.

The engine was mainly used in the F-150 up to 2023 and it also powered the Explorer in the form of a hybrid powerplant. Another possible use was the Police Interceptor. The engine was discontinued due to poor fuel efficiency and some design flaws.

Key features and my opinion:

• Production years:2018-2023
• Average lifespan of 3.3L V6 Duratec:200,000-230,000 miles
• Fuel supply type:direct injection
• Power range:285-290 hp
• Fuel efficiency:average
• Engine block material:aluminum
• Engine reliability score:medium
• The most common problems:water pump failure, phasers are pretty weak, oil leaks are common.

Ford 2.0L Duratec engine

While a lot of different engines may be considered Ford Duratec 2.0L engines, I will be talking here about the Mazda L engine. This is the legendary machine that became the base for a lot of different technologies, including the iconic EcoBoost series of engines.

The Mazda L engine was developed by Mazda and later used by Ford and other manufacturers under different names. The most common engine under the hood of Ford cars in the world is the 2.0 Duratec. This engine became the base for the Duratec 20 engine which is most widely known thanks to the Ford Focus third generation.

The engine is very reliable and has little to no serious problems till it reaches high mileage. After that, numerous issues can come at once and make your Ford just impossible to own.

Key features and my opinion:

• Production years:2001-2022
• Average lifespan of 2.0L Duratec:190,000-220,000 miles
• Fuel supply type:direct injection
• Power range:130-150 hp
• Fuel efficiency:average
• Engine block material:aluminum
• Engine reliability score:medium
• The most common problems:oil consumption, chain stretching, carbon buildup on intake valves.

Ford 2.3L Duratec engine

This Duratec engine was also derived from the Mazda L powerplant. The difference is that it wasn't used as widely as the 2-liter version.

This is a simple engine, some of its versions had intake variable valve timing while some didn't have it at all. The simple fuel supply is an important advantage - you could expect this powerplant to last for ages if you maintain it well and regularly.

There are no hydraulic lifters, the cams are driven by the chain. While this is a very decent and long-lasting 4-cylinder engine, it's not very economical. Owners say that the real-world consumption is the same as in many more powerful V6 engines.

Key features and my opinion:

• Production years:2001-2011
• Average lifespan of 2.3L Duratec:230,000-260,000 miles
• Fuel supply type:port injection
• Power range:153-178 hp
• Fuel efficiency:bad
• Engine block material:aluminum
• Engine reliability score:high
• The most common problems:oil consumption, chain stretching, phaser problems, no lifters.

Ford 1.6L Sigma engine

The Sigma engine (or 1.6 Duratec Ti-VCT) is very well-known in the US thanks to powering the Ford Fiesta 7th generation - one of the most popular compact sedan and hatchback cars on the market.

This is a very decent and simple engine with port injection, no turbo, optimal power and torque for everyday use. The only problem is the consumption - it's the same as with the 2-liter Focus engine.

The Ti-VCT technology means that the phasers are present in both camshafts. The cams are driven by the belt which is important to replace on time to avoid fatal failure. Also, the Sigma engine is quite durable. It was used in dozens of Ford models all over the world for much more than a decade.

Key features and my opinion:

• Production years:2008-2023
• Average lifespan of 1.6L Sigma:210,000-230,000 miles
• Fuel supply type:port injection
• Power range:108-133 hp
• Fuel efficiency:average
• Engine block material:aluminum
• Engine reliability score:high
• The most common problems:phasers are faulty, ignition issues, electrical problems, oil leaks, minor issues.

Ford 3.5L V6 PowerBoost engine

You may have heard about the PowerBoost engine offered by Ford in its latest generation of the F-150 truck. This is the 3.5L EcoBoost V6 engine that offers the hybrid technology in it.

Later, I will review the 3.5L EcoBoost engine but now I will focus on what's different in the PowerBoost. So, the hybrid engine offers absolutely the same twin-turbo V6 architecture but Ford added the regenerative braking, the Li-Ion battery pack, and the 47-hp electric motor for support and improvement of driving.

The PowerBoost engine offers better torque, way better gas mileage in the city traffic, and also much more efficient use of energy.

Key features and my opinion:

• Production years:2021-now
• Average lifespan of 3.5L V6 PowerBoost:200,000-240,000 miles
• Fuel supply type:direct injection
• Power range:430 hp
• Fuel efficiency:good
• Engine block material:aluminum
• Engine reliability score:medium
• The most common problems:oil leaks, turbocharger failure, overheating, spark plugs and ignition coils failure.

Ford 1.0L EcoBoost engine

The 1-liter EcoBoost Fox is the smaller turbo engine in the Ford's lineup. This is the 3-cylinder engine with, surprisingly, cast-iron block and the wet-belt assembly.

The wet timing belt means that the belt is lubricated by oil which is pretty unusual. Thanks to this, Ford claims the belt may survive up to 150,000 miles but it's a very brave solution. If the belt breaks, it will destroy the engine.

There are no hydraulic lifters but there are twin independent phasers on both camshafts. The engine is efficient and can produce good power but it's not that durable. There are mild-hybrid versions that are currently in use in the UK and also sports versions of this engine.

Key features and my opinion:

• Production years:2012-now
• Average lifespan of 1.0L EcoBoost:150,000-200,000 miles
• Fuel supply type:direct injection
• Power range:84-153 hp
• Fuel efficiency:excellent
• Engine block material:cast-iron
• Engine reliability score:medium
• The most common problems:coolant leaks, oil leaks, carbon buildup on intake valves, turbocharger failure, no lifters.

Ford 1.5L 4-cylinder EcoBoost engine

So, there are two 1.5L EcoBoost engines - the older one has 4 cylinders, and the newer one - 3 cylinders. Now, let's talk about the 4-cylinder model.

This engine was made for the Fusion in 2014 and was a try to get rid of the awful 1.6L EcoBoost engine that appeared to be a nightmare for the company and all owners The engine was then also used in other vehicles like the Focus, Escape, C-Max, and other models in various markets.

The engine got a very tricky water pump with electronic control that was aimed at shortening the warm-up time for safe use. But it became one of the common problems. Overall, the durability and reliability are quite good if you compare it with other small turbo engines on the market.

Key features and my opinion:

• Production years:2014-now
• Average lifespan of 1.5L 4-cylinder EcoBoost:140,000-190,000 miles
• Fuel supply type:direct injection
• Power range:148-181 hp
• Fuel efficiency:good
• Engine block material:aluminum
• Engine reliability score:low
• The most common problems:overheating issues, head gasket failure, water pump problems, engine knocking issue, carbon buildup on intake valves, no lifters.

Ford 1.5L 3-cylinder EcoBoost engine

The 3-cylinder 1.5L EcoBoost engine is the enlarged 1.0L Fox engine. So, it has everything in common with the little brother. But the timing system and block material. The timing belt is changed to the chain and the wet belt is still there but it only drives the water pump, not the camshafts. The block here is aluminum.

Other than that, it's the same engine with the Ti-VCT phasers on both cams, turbocharger, aluminum block, etc. Also, the interesting thing about the Dragon engine is that it has a cylinder deactivation system. Yes, the 3-cylinder engine with the cylinder deactivation system...

The 1.5L EcoBoost Dragon engine was developed for the Ford Fiesta ST in Europe but since then it has also been used in the Focus, Escape, Puma ST, and in some rally-oriented cars by Ford.

Key features and my opinion:

• Production years:2017-now
• Average lifespan of 1.5L 3-cylinder EcoBoost:150,000-190,000 miles
• Fuel supply type:direct injection
• Power range:150-200 hp
• Fuel efficiency:good
• Engine block material:aluminum
• Engine reliability score:medium
• The most common problems:cylinder deactivation mode problems, vibrations, various electrical issues, turbocharger problems.

Ford 1.6L EcoBoost engine

The 1.6L EcoBoost was a pretty obvious move from Ford to build some small and all-purpose engine with decent power. But they failed to make it reliable. The simple turbocharged engine doesn't seem to be problematic at first, but in reality, it's the engine you should avoid.

The majority of 1.6L EcoBoost engines were recalled due to the risk of fire because of the flaw in the water pump design. Other than that, the engine seems simple: aluminum block, belt-driven camshafts, phasers on both cams, no hydraulic lifters, BorgWarner turbo with intercooler.

The paradox thing is that Ford still makes this engine and offers it in some markets. Not in the US, of course. Also, Volvo has been using this engine heavily in its entire lineup of small cars.

Key features and my opinion:

• Production years:2010-now
• Average lifespan of 1.6L EcoBoost:160,000-190,000 miles
• Fuel supply type:direct injection
• Power range:118-197 hp
• Fuel efficiency:good
• Engine block material:aluminum
• Engine reliability score:low
• The most common problems:risk of catching fire, overheating problems, coolant leaks, no lifters, turbocharger failure.

Ford 2.0L EcoBoost engine

The 2-liter EcoBoost engine exists in two incarnations: the first-ever EcoBoost engine derived from the Mazda L engine and the twin-scroll turbo powerplant used in the majority of modern Ford vehicles.

So, the first one was pretty old-fashioned. This was the simple old engine that got a turbocharger and the Ti-VCT phasers. Other than that, it still was the old engine with pretty good durability but poor efficiency. But thanks to the fact that the 2.0L engine showed the power and torque of the 3-liter V6 of that time, the engine was widely used in Ford, Lincoln, Volvo, Jaguar, and even Land Rover vehicles.

The twin-scroll 2.0L EcoBoost engine was presented in 2015. It was completely redesigned: new block, new head, new fuel supply, and new lubrication systems. Thanks to higher low-end torque, the engine could now be used in larger cars and still feel pretty powerful.

Key features and my opinion:

• Production years:2010-now
• Average lifespan of 2.0L EcoBoost:150,000-200,000 miles
• Fuel supply type:direct injection
• Power range:160-301 hp
• Fuel efficiency:average
• Engine block material:aluminum
• Engine reliability score:medium
• The most common problems:intake manifold problems, turbocharger failure, carbon intake on intake valves, weak phasers, engine knocking issues.

Ford 2.3L EcoBoost engine

The 2.3-liter EcoBoost engine is the largest 4-cylinder engine in the family. It's pretty popular due to its wonderful power and torque and still very pleasant gas mileage.

The engine is pretty simple. It has chain-driven camshafts with phasers on each cam. There are no hydraulic lifters. The turbocharger is set to deliver maximum power and wonderful low-end torque. But the focus on performance made this engine pretty weak in terms of its overall life expectancy.

The powerplant has been used in different Ford and Lincoln vehicles as well as in racing cars like VUHL, Dallara, Zenos, etc.

Key features and my opinion:

• Production years:2015-now
• Average lifespan of 2.3L EcoBoost:120,000-140,000 miles
• Fuel supply type:direct injection
• Power range:270-395 hp
• Fuel efficiency:average
• Engine block material:aluminum
• Engine reliability score:low
• The most common problems:fatal overheating issues, very unreliable fuel supply system, turbocharger failure.

Ford 2.7L V6 EcoBoost engine

The 2.7 EcoBoost Nano engine has two generations. The first one was introduced in 2015 and had a very interesting block design. The upper part of the block is made of graphite iron while the lower one is made of aluminum.

The next generation appeared in 2018. The most important change was the addition of the port injectors to avoid carbon buildup on valves. Also, the torque became higher. Another addition was the EGR system which was aimed to improve the emission features of the new engine.

The chain problems in the first-gen 2.7 EcoBoost were solved by introducing the dual-chain camshafts system. The oil pump is still driven by a separate belt and is very technological for better efficiency. Upgrades are more than possible. Fuel economy is pretty good.

Key features and my opinion:

• Production years:2015-now
• Average lifespan of 2.7L V6 EcoBoost:190,000-240,000 miles
• Fuel supply type:direct injection (later combined direct + port injection)
• Power range:315-330 hp
• Fuel efficiency:average
• Engine block material:cast-iron
• Engine reliability score:medium
• The most common problems:valvetrain problems, issues with electronics, oil consumption, power loss.

Ford 3.0L V6 EcoBoost engine

The 3-liter EcoBoost engine was derived from the 2.7L Nano, so it's also called Nano. It has a larger displacement but eventually, this is absolutely the same engine with some more power and higher torque.

The engine has the same construction, the head is identical. The block is all-aluminum but other than that it's identical to the 2.7L Nano. The engine will also have the same problems with valves and electronics.

The main goal of making this engine for Ford was to replace the inefficient 3.7L non-turbo Duratec engine in the majority of the vehicles. This helps Ford establish its new engine families as more efficient and eco-friendlier.

Key features and my opinion:

• Production years:2017-now
• Average lifespan of 3.0L V6 EcoBoost:200,000-240,000 miles
• Fuel supply type:direct injection
• Power range:350-550 hp
• Fuel efficiency:average
• Engine block material:aluminum
• Engine reliability score:medium
• The most common problems:valvetrain problems, issues with electronics, oil consumption, power loss.

Ford 3.5L EcoBoost engine

The 3.5L EcoBoost is the largest engine in the family. Its first generation appeared in 2010 and was the revolution in V6 Turbo engines. This engine was aimed to substitute all V8 non-turbo engines offered by Ford, at least in non-performance vehicles.

Actually, the first generation of the engine overall wasn't as successful as Ford initially thought. But it's a great powerplant and it's probably one of the most reliable EcoBoost engines in the family.

This powerplant uses the Duratec 35 engine and adds a turbocharger to it along with some significant upgrades. There are different turbo settings with Borg Warner and Garrett units - each engine has two turbos. It requires perfect oil only. 

The second generation is known as the D35 engine. It was first shown in 2017 and the most interesting part of it is the performance part. It's a crazy performance-oriented engine with an immense amount of power and abnormally high torque. Its task is to replace all performance V8 engines in the Raptor and GT models for better MPG.

More than one owner reported mysterious ticking noises. Also, a lot of reports have been made about coolant leaks.

Key features and my opinion:

• Production years:2010-now
• Average lifespan of 3.5L EcoBoost:190,000-220,000 miles
• Fuel supply type:direct injection
• Power range:310-660 hp
• Fuel efficiency:average
• Engine block material:aluminum
• Engine reliability score:medium
• The most common problems:intercooler problems, timing chain stretching, carbon buildup on intake valves, coolant and oil leaks, cam phaser issues.

Ford 7.3L Godzilla engine

The Godzilla V8 engine is one of the new engines in the Ford lineup that was offered in 2020 to substitute older Boss and Modular families of big engines.

This is the commercial engine and it's mainly used in the F-Series super-duty trucks and also E-Series vehicles. Also, Ford offers the Godzilla as the crate engine, so owners of older trucks may buy it to replace the old V8 or V10 engine.

The Godzilla offers variable valve timing, an iron block, a very simple fuel injection system, a lot of different tuning options for power and torque. The engine is great in terms of its potential durability and flexibility. But the fuel economy is really awful.

Key features and my opinion:

• Production years:2020-now
• Average lifespan of 7.3L Godzilla:400,000-500,000 miles
• Fuel supply type:port injection
• Power range:300-430 hp
• Fuel efficiency:awful
• Engine block material:cast-iron
• Engine reliability score:high
• The most common problems:phasers are faulty, oil and coolant leaks, enormous fuel consumption, lifter issues.

Ford 4.0L Cologne V6 engine

The Cologne family of engines started back in 1962. The 4-liter V6 engine was used in Ford and Mazda vehicles. There are several modifications with different head designs.

Interestingly, Ford used this engine for trucks and also for performance models. You could find the 4.0L Cologne V6 engine under the hoods of the Ranger, Aerostar, Explorer, Courier, and even Mustang. Also, the Land Rover Discovery used the same engine.

It's called Cologne for being produced in Cologne, Germany. But the 4-liter version was mainly used in US vehicles. The last such engine was installed in a Ford car in 2010.

Key features and my opinion:

• Production years:1990-2010
• Average lifespan of 4.0L Cologne V6:230,000-260,000 miles
• Fuel supply type:port injection
• Power range:160-216 hp
• Fuel efficiency:awful
• Engine block material:cast-iron
• Engine reliability score:high
• The most common problems:very noisy work, timing chain issues, weak cylinder head, various leaks.

Ford 3.8L V6 Essex engine

The 3.8L V6 engine was first introduced in 1982 and it's a very old classic engine with no modern technologies. Even though it's very reliable and can go longer than anything else in your car, this powerplant loves drinking fuel as fast as it possibly can.

The last known use of the 3.8L V6 engine was the Ford Windstar in 2003. There was also a supercharged version that existed for several years.

In the first years, this engine was equipped with carburetors. The injection version (single-point injection) was introduced in 1996. Almost all Essex engines are dead now due to their age. But some still keep running having sometimes over 500K miles on dashboards.

Key features and my opinion:

• Production years:1982-2003
• Average lifespan of 3.8L V6 Essex:280,000-320,000 miles
• Fuel supply type:carburetor, later -port injection
• Power range:120-190 hp
• Fuel efficiency:bad
• Engine block material:cast-iron
• Engine reliability score:high
• The most common problems:a lot of possible leaks, vibrations, insanely low power.

Ford 3.9L V6 Essex engine

The 3.9L Essex V6 engine wasn't that popular because it was only produced for several years. Basically, this is exactly the same engine as the 3.8L Essex but with a slightly longer stroke. The block and the head were just identical.

The engine was introduced in 2004 as the revised generation of the Essex engine family and it was initially used in the Mustang. But then, the Mustang got the 4.0L Cologne engine and the Essex was only installed in the Freestar. In 2007, the company discontinued the 3.9L V6 due to its poor efficiency.

Basically, there is nothing that would be very different from the previous engine.

Key features and my opinion:

• Production years:2004-2007
• Average lifespan of 3.9L V6 Essex:280,000-320,000 miles
• Fuel supply type:port injection
• Power range:190 hp
• Fuel efficiency:bad
• Engine block material:cast-iron
• Engine reliability score:high
• The most common problems:a lot of possible leaks, vibrations, low power.

Ford 460 engine

The 460 engine is part of the 385 engine family - the V8 engine that started in 1968 and lived about 30 years in various production lines of Ford Motor Company.

We may still know this engine for powering the old E-Series vans and F-Series heavy-duty trucks. The last such engine was made in 1997. Of course, till today, they are almost all dead or sent to scrapyards because of very poor efficiency as compared with any modern engine.

This engine was eventually replaced by the V10 which I've already described earlier in this article.

Key features and my opinion:

• Production years:1968-1997
• Average lifespan of 460:350,000-500,000 miles
• Fuel supply type:carburetor, later - port injection
• Power range:197-245 hp
• Fuel efficiency:awful
• Engine block material:cast-iron
• Engine reliability score:high
• The most common problems:various oil leaks, coolant leaks, overheating, fuel injection problems, enormous fuel consumption.

Ford 2.5L Hybrid engine

The 2.5L 5-cylinder hybrid engine used in several modern vehicles by Ford is basically the Duratec iVCT series engine. The simple and reliable gasoline engine may be equipped with different hybrid technologies thanks to employing the Atkinson cycle.

The engine offers limited power but it's very reliable and durable. Also, it works perfectly as part of almost any hybrid powertrain. Thanks to this, such vehicles as the Maverick or the Escape hybrid may enjoy great reliability and wonderful efficiency.

This is also the Mazda L series engine. It's as old as me and has only one phaser on intake camshaft. There is the chain in the timing system, no lifters, no turbo. The injection is simple multi-point. There is basically nothing to worry about in this engine.

Key features and my opinion:

• Production years:2008-now
• Average lifespan of 2.5L Hybrid:220,000-250,000 miles
• Fuel supply type:port injection
• Power range:168-175 hp
• Fuel efficiency:excellent
• Engine block material:aluminum
• Engine reliability score:high
• The most common problems:various oil leaks, noisy work, timing chain problems, phaser problems.

Ford 7.3L IDI engine

One of the oldest diesel engines we still can see working is the old good 7.3-liter IDI engine. This is the predecessor of the Power Stroke often called International Harvester IDI.

It was first shown in 1987 and then in 1993 it also got a turbocharged version. The engine wasn't developed eventually because Ford launched its Power Stroke series of diesel engines and didn't see the reason to invest money into a similar project.

So, the IDI engine was commonly used in school buses, heavy trucks, special equipment, etc. But the engine was really durable and could withstand almost anything, so some of them are still alive. They are even widely used for upgrades.

Key features and my opinion:

• Production years:1987-1994
• Average lifespan of 7.3L IDI:450,000-500,000 miles
• Fuel supply type:indirect injection
• Power range:185-190 hp
• Fuel efficiency:awful
• Engine block material:cast-iron
• Engine reliability score:high
• The most common problems:very sensitive fuel injection system, bad fuel consumption, oil leaks, extremely poor power.

Ford 7.3L Power Stroke engine

The 7.3L Power Stroke diesel engine was introduced in 1994 and it replaced the old and outdated 7.3 IDI. It was only aimed at the Econoline vans and F-Series trucks.

The engine had completely different engineering from the IDI engine and only shared displacement with it. The engine appeared to be very reliable and durable. It's one of the best diesel engines ever put in a light-duty truck in history, according to many experts.

Still, the 7.3L Power Stroke had its problems. The camshaft position sensor could malfunction and it may have led to engine death. A lot of problems were found with electronics, actuators, wiring, etc.

Turbocharger was also pretty faulty. A lot of problems with wastegate have been registered. Also, I've written about the IPR valve issues in this engine. Unfortunately, injectors weren't perfect and causes some issues.

Another common issue is the lift pump problem - pretty unusual.

Key features and my opinion:

• Production years:1994-2003
• Average lifespan of 7.3 Power Stroke:380,000-450,000 miles
• Fuel supply type:direct injection
• Power range:250-275 hp
• Fuel efficiency:bad
• Engine block material:cast iron
• Engine reliability score:high
• The most common problems:electronics problems, wiring issues, pretty bad fuel economy.

Ford 6.0L Power Stroke engine

In 2003, Ford understood that the 7.3 Power Stroke was too huge and not really efficient anymore. So, the company decided to upgrade it and eventually made the 6.0L engine.

This is the turbocharged V8 diesel engine with some serious upgrades in terms of fuel supply and valvetrain. It became much more efficient than the 7.3L version. Also, this engine managed to get under the hoods of more models.

But Ford had problems with the 6.0L Power Stroke and had to pay out huge lawsuit payments. There were even fraud cases initiated in courts all over the US. The reason for this is the huge number of different problems. So, the engine was quickly discontinued and the 6.4L appeared on the stage.

Owners often upgrade turbos due to inefficiency of the stock turbochargers.

Key features and my opinion:

• Production years:2003-2009
• Average lifespan of 6.0L Power Stroke:320,000-350,000 miles
• Fuel supply type:direct injection
• Power range:325 hp
• Fuel efficiency:bad
• Engine block material:cast-iron
• Engine reliability score:low
• The most common problems:EGR cooler and oil cooler problems, fuel pump issues, head gasket problems, oil pump failing.

Ford 6.4 Power Stroke engine

The next diesel engine for trucks and commercial vehicles after the awful 6.0 Power Stroke was the 6.4L Power Stroke unit. It was introduced in 2008.

This was the first dual-turbo diesel engine for commercial use on the market. And this was the first Ford diesel engine with the DPF to enhance its eco-friendliness. Sounds fun when you think of its displacement and the amount of diesel fuel it burns.

Also, this generation changed the fuel supply system to the much more reliable Common Rail. Anyway, the injectors remained not so durable and very expensive to replace.

The 6.4L Power Stroke was mainly used in the Ford F-Series Super Duty trucks and different commercial vehicles. But it had a myriad of problems that it inherited from its predecessor as well as developed new ones. Esepcially, the ones with the turbochargers.

Key features and my opinion:

• Production years:2008-2010
• Average lifespan of 6.4 Power Stroke:230,000-250,000 miles
• Fuel supply type:Common Rail
• Power range:350 hp
• Fuel efficiency:bad
• Engine block material:cast-iron
• Engine reliability score:low
• The most common problems:oil consumption, turbo problems, EGR problems, DPF issues, high cost of maintenance, poor fuel economy.

Ford 6.7L Power Stroke engine

The Power Stroke family of engines represents diesel powerplants, mainly the big ones that were made for heavy-duty tasks. The 6.7 Power Stroke is one of the most successful engines in the lineup.

It replaced the 6.4 Power Stroke in 2011 and was initially used in F-Series trucks for heavy-duty use (F250 to F550). This is the engine made by a whole bunch of different companies but eventually, Ford got a pretty decent machine with wonderful torque and more than acceptable durability.

In 2015, there was a major update and the company changed almost everything in this engine. But still, it didn't survive that long on the production lines due to emission features and the need to move further. Also, a lot of owners noticed the air-in-fuel problem. Sometimes, the engine may seem dead with no crank, no start.

Traditionally for all Power Stroke engines, the injectors loved failing.

Key features and my opinion:

• Production years:2011-2016
• Average lifespan of 6.7 Power Stroke:240,000-270,000 miles
• Fuel supply type:Common Rail
• Power range:330-475 hp
• Fuel efficiency:average
• Engine block material:cast-iron
• Engine reliability score:medium
• The most common problems:turbo problems, cooling system issues, weak sensors, CP4 pump problems, intercooler problems.

Ford 3.2 Power Stroke engine

This is the modern diesel engine with 5 cylinders and in-line configuration. The engine was first shown in the Transit in the US in 2015. Actually, this is the Duratorq engine from Europe but with some modifications to meet the US ecology rules.

This is a pretty standard modern diesel engine with a lot of questions about its durability due to the focus on emission standards. It has the EGR and DPF and also you will need DEF to drive your vehicle.

While these engines are way more economical and efficient, they won't last as long as the older Power Stroke engines could last despite their all problems.

Key features and my opinion:

• Production years:2015-2019
• Average lifespan of 3.2 Power Stroke:220,000-250,000 miles
• Fuel supply type:Common Rail
• Power range:185 hp
• Fuel efficiency:good
• Engine block material:cast-iron
• Engine reliability score:medium
• The most common problems:EGR problems, DPF issues, expensive fuel injection repair, glow plugs failing.

Ford 3.0L Power Stroke engine

This is the last Power Stroke engine called Lion. The first time we could see this unit on sale was in 2018. The engine was discontinued in 2021 due to low demand in the US. Interestingly, all 3.0L V6 Power Stroke engines were manufactured in England.

This is the standard modern diesel engine and there is nothing extraordinary in it. It's good to drive with proper power, wonderful towing capacity. But it's bad to own when the mileage is high. There are a lot of minor issues that are sometimes very expensive to solve.

The engine powered the F-150 truck only. Anyway, owners loved the engine and the fuel consumption. But they still point out a lot of common issues.

Key features and my opinion:

• Production years:2018-2021
• Average lifespan of 3.0 Power Stroke:180,000-220,000 miles
• Fuel supply type:Common Rail
• Power range:250 hp
• Fuel efficiency:good
• Engine block material:cast-iron
• Engine reliability score:medium
• The most common problems:EGR problems, coolant leaks, oil consumption, DPF issues, problems with electronics.

Ford 2.0 EcoBlue engine

The 2.0L EcoBlue bi-turbo engine is the Ford Ranger engine in Europe. This is the diesel unit that gives emotions, not just practical driving.

Such engines also power the Ranger Raptor, Everest, Galaxy, Edge, and S-Max - all outside the US.

The unit doesn't offer monstrous power but its torque is unbelievable. The addition of the extra turbocharger to the already turbocharged base engine seems to transform it into some kind of a diesel monster. But it's just the small 4-cylinder engine.

Of course, such boosting affects the overall durability of the engine.

Key features and my opinion:

• Production years:2018-now
• Average lifespan of 2.0 EcoBlue:150,000-170,000 miles
• Fuel supply type:Common Rail
• Power range:210-235 hp
• Fuel efficiency:good
• Engine block material:cast-iron
• Engine reliability score:medium
• The most common problems:turbocharger problems, EGR issues, DPF clogging, issues with electronics, oil leaks and consumption.

Ford 1.4 TDCI engine

The 1.4 Duratorq TDCI engine is a purely European powerplant that was mainly used in the Fiesta and also other small cars based on the same platform. The engine is small but it has proper torque, so driving such a vehicle is always fun.

Ford offers a very simple diesel engine with its single camshaft being driven by the belt. There are no phasers for this engine. But there are hydraulic lifters. The BorgWarner turbocharger does a good job of boosting torque.

Actually, such TDCI engines proved to be extremely efficient in terms of fuel consumption and still pretty durable. That's why, the Fiesta in Europe was mainly bought with the 1.4 TDCI engine option under the hood.

Key features and my opinion:

• Production years:2002-now
• Average lifespan of 1.4 TDCI:180,000-200,000 miles
• Fuel supply type:Common Rail
• Power range:67 hp
• Fuel efficiency:excellent
• Engine block material:aluminum
• Engine reliability score:medium
• The most common problems:very tricky fuel supply system, bad oil consumption, turbocharger problems, engine mount issues.

Ford 1.6 TDCI engine

The 1.6L diesel (TDCI) engine belongs to the same family as the previously described 1.4 TDCI. This is a more powerful diesel engine that still has 4 cylinders and it was used by a plethora of car makers such as Ford, Mazda, Volvo, Mini, Peugeot, and Citroen.

The engine is still simple in its design and pretty reliable. We can see the chain plus belt timing system. Also, there are hydraulic lifters to adjust valves. Still, no phasers are included. The turbocharger is more efficient and is equipped with an intercooler.

Other than that, the engines are identical. Since the 1.6L one offers more power, owners don't rev it up too much. But still, the longevity is the same or even lower because the bigger engine powers bigger and heavier cars.

Key features and my opinion:

• Production years:2002-now
• Average lifespan of 1.6 TDCI:170,000-190,000 miles
• Fuel supply type:Common Rail
• Power range:108 hp
• Fuel efficiency:excellent
• Engine block material:aluminum
• Engine reliability score:medium
• The most common problems:very tricky fuel supply system, bad oil consumption, turbocharger problems, timing chain stretching, coolant leaks.
