Why Ford Ecoboost Engines Fail

Here’s a full teardown of Ford’s Ecoboost 2.0L Engine to see what’s inside and how it works!
The Ford Ecoboost line of engines was loosely based on Mazda’s L series of 4 cylinder all aluminum engines. In 2015, Ford updated this engine as it is currently used in production vehicles today. In this teardown we examine the main components and its construction, including its dual VVT valve train, cylinder head, integrated exhaust manifold, turbocharger, intake, direct injection system, cylinder block and lubrication system, crankshaft, balancer assembly and oil pan.
While some external pieces vary between applications, most of the internal pieces are the same. As far as reliability, common issues will be carbon buildup, turbocharger manifold leaks, fuel pumps failing (both low and high pressure) and turbo boost controller solenoids failing.
The engine in this video was from a 2016 Ford Focus ST, which may have been subjected to water intrusion from the PCV catch can. The engine did not show any signs of damage or water internally.

People wonder why I still drive my old beater, it's because the engine is solid and everytime I think of buying something else I Google it and this guy has a whole video detailing why I shouldn't. He's saved me a fortune.

[@huskers1278]

You honestly have to remember one thing when saying that. People hardly EVER maintain their vehicles. Ford recommends oil changes every 10k miles or 1 year whichever comes first for this motor. I would never in a million years follow that myself because that's how you end up with a blown motor. Also this motor obviously was fine and whoever sold it was a moron and was sure it hydro locked and probably didn't even check compression. Lots of motors can have issues but generally people don't maintain anything which is why I'll never own a used vehicle again.

[@colubrinedeucecreative]

@@huskers1278 Aren't they running special syth oil blends these days? Then you might say people might not use the right oil or deal with the dealer to do it, and with everyone having the iternet now you have the uniformed most likely to post, and less of the ones that don't have problems.

[@huskers1278]

@TOPHERHARPER From the factory, it uses a synthetic blend Motorcraft 5w30 Syn Blend to be exact. I personally run Pennzoil Platinum Ultra which is full synthetic and oil has come A LONG WAY since the 70s-2000s but no motor that uses a turbo should ever exceed 5k miles on oil. Especially when you live in the city these direct injection motors get lots of fuel deposits in the oil and it makes it lose its lubricity. And you are correct often times you read online about issues someone is having with a specific vehicles motor but you don't read the 1000s that never had a problem. People are dramatic and engines are so far and above superior to what they were 20 years ago it's not even funny. More often than not a vehicle breaking has everything to do with the owners' maintenance or lack thereof.

[@andrewt9204]

@@huskers1278 True, most of us here are probably good about maintenance, which goes such a long way especially with these newer engines. I'm amazed at how many people I've known that call and ask "what does it mean when the oil light flashes on and off? Does that mean I need to change it?" Uhhh no, it means you haven't got any oil in there, and you've likely just took tens of thousands of miles of life off the thing. How long ago did you change it? "Umm, it's been a couple years I think". I'm just flabbergasted. Like don't you care about protecting your expensive investment?? I've also seen enough of the "just rolled in" youtube channel to lose faith in responsible owners. I know there's freak mechanical failures and defects, but I bet a lot stems from neglect.

15:44 - This was definitely a weak spot with this engine. I can't tell you how many 2.0 turbos I had to replace while working for Ford. Either the manifold cracked or the wastegate failed both were common failures around 60K miles. Since it was a one-piece assembly and very time consuming to replace, it was a costly repair ($1800). Ford really killed their already deteriorating reputation with this engine. It was used on their most popular vehicles and either the turbo failed, or the slotted cooling block would fail all at an early mileage or just beyond warranty coverage. Leaving owners with a vehicle that needs a new engine to the tune of $8000.

[@LA_Commander]

Wow, I must admit I'm very impressed with how strong and well-built this engine is! I didn't know it had that strong of a bottom end. A few points should be made about this motor because I think it gets a bad rap sometimes: 1) Use premium fuel with this engine. LSPI is a known problem with this motor so why cheap out and try and save 30-40 cents a gallon and risk that? Use premium fuel with these turbocharged motors. Your engine will run better. 2) Use quality full synthetic oil. Don't cheap out and get regular dollar store oil. You can see how the engine oil is used not only to lubricate the engine, but it also to cool the engine and, most critically, the turbocharger itself. Use a high quality full synthetic oil. Make sure the oil has an ASI "SP" rating. That's the latest and greatest. It was developed for these TDI motors. 3) Change your oil every 4,000 to 5,000 miles! Don't let this go! People don't change their oil and then they wonder why they have sludge and other crap in their engines and they get ruined. These modern, complex motors require clean, fresh oil with a sophisticated additive package. Fuel dilution is a problem with these TDI motors. So, change that oil!!

I love your no time lost teardown technique, fast and effective. You need a big air rattle gun for the tough bolts. I played the piston section of your video several times, it looks to me that the scraper rings were soft. Perhaps an engine that had been over heated without being fried. Otherwise rather sad that an engine in good nick got scrapped.

[@TheEulerID]

Given there were epic levels of carbonisation, I wonder if the turbo oil seals had failed and oil was being sucked into the inlet manifold. That's not uncommon with turbos, but it would have been accompanied by lots of blue smoke. One thing is for sure, that engine was not hydrolocked. If it had been, then there would probably have been a bent rod, and there would have been a lot of water, either in the cylinders or, possibly, in the sump. No sign of any of that.

[@B1GDaddyFatStax]

The carbon buildup in the intake runners isn't limited to just EcoBoost engines. It's pretty much anything direct injected. What causes it is the PCV system and a lack of fuel being sprayed down the ports like the traditional ported injection systems. The oils from the PCV system get recycled into the intake and deposit onto the runner surfaces. Then, the heat from the head bakes those deposits, carbonizing them. Traditionally in port-injection, the fuel gets sprayed into the runners and onto the backsides of the valves helping to keep them clean. As a D.I. engine ages it burns more oil and allows more blowby, thus increasing the volume of PCV gases into the intake. The catch can is a way to minimize the vaporized oils in the PCV system from making their way into the intake. This is also why Ford dealerships(among others) tend to recommend fuel injection and upper intake services. It's preventative maintenance on the intake system that helps to reduce the buildup.

[@B1GDaddyFatStax]

@@MFcitrous EGR has always been a challenge in the automotive industry. However, the carbon buildup on direct injected engines is significantly worse than their ported counterparts. While EGR can leave deposits on the valves, it has been manageable up to this point. Once you take away the cleaning effect of ported injection, it does get worse, but now with added cylinder pressures of boosted engines and lighter weight oils, blowby has increased significantly to allow even more PCV gasses to accumulate. You also have to remember EGR gasses are mostly carbon only deposits. PCV gasses are mostly unburnt oils etc. This is where the gummy residue comes from that leads to excessive buildup.

[@0Meaty]

Thanks for the informative response Joe's garage! That was the big question I had: what causes the carbon build up on the intake runners and ports. It "might" explain why Toyota now have both port and direct injection on their 2.5 liter 4 cylinder hybrid engines.

The ecoboost engine in my 2014 Ford Escape is a great engine. Since it is turbocharged, I make that I let it spin up and spin down for a few minutes before I take off and when I park. This helps to extend the engine life. Unfortunately, a lot of people don't allow the engine and turbocharger this short rest time, which will definitely be expensive and destructive.

[@bonedatt]

You are absolutely correct with regards to driving your car conservatively for a few minutes for the engine to get to normal operating temperature, but I don't think you need to wait for it to cool off before turning your engine off. The stop and go traffic driving before you get to your parking lot or drive way, is enough to cool the turbo down.

Since each pulse basically supercools the cylinder, manufacturers have gotten to the point of increasing compression ratios up to something like 10:1 while also attaching a 15-25psi turbo. Try that with a legacy port injected engine and the heat will warp the head. Also, trying to squeeze so much power out of such a small platform just means extreme wear over time. A 5.0 V8 pumping 300hp can go 300k+ miles easily with maintenance, but a 2.0 I4 pushing about the same power? Good luck passing 200k miles with anything short of perfect maintenance and constant baby-ing it. At this point its just physics. You cant have great power and great mileage without sacrificing reliability. This is also why warranty coverage over time has gotten smaller. You just don't get the longevity anymore. It just isn't possible. Honestly I would take the bigger displacement packages and the hit on mileage to know my vehicle will last. But with how expensive everything is now, and how much people have to stretch, I understand why it has come to this.

It is absolutely incredible how complicated a modern engine is, totally impressive.

[@ZipZoomZip]

How can you call a complicated engine that burns gasoline and needs all kinds of regular maintenance and repairs, "modern"? It requires huge, expensive oil refineries to make the fuel too. An electric car can just be plugged into some panels on top of your roof to drive you around for another week, no pistons, no spark plugs, no air filters, no pcv valves, no ignition wires, no fuel pump, no oil changes and no refineries needed. And on a cold day you don't have to worry that it might not start. I've been driving electric going on 5 years now and could never go back! One tip I can give you: If you want to take long trips without inconvenience, make sure it's a Tesla! Tesla said they were planning to open their fast chargers up to non-Tesla but there is no telling how long that might take or whether all of their chargers would be in the sharing program.

[@Neil-Aspinall]

@@ZipZoomZip Thanks for the rant Mull. I was just making a general statement about benzine/diesel engines in general. Electric cars are not the environmentally friendly vehicles they are made out to be if you look int it. I have driven 4 different Teslas and I must say they are the funnest cars I have ever driven. I would worry about the battery in extreme cold conditions though.

[@ZipZoomZip]

@@Neil-Aspinall I'm a snow skiing enthusiast so my cars see lots of extreme winter conditions in the mountains. That is par for the course for someone who loves fresh winter powder because that means winter storms. I don't have to worry about my Tesla starting on a frigid winter morning or after being buried in a snow drift all day or all day/night. It just goes. I cannot say the same about the old-fashioned gasoline engine. I never worry about my battery in the extreme cold, this is a made up reason why EV's are not viable, it is not a problem. There are a number of reasons why my Tesla is the best ski car I've ever had out of a long list of VW's, Volvo's, Subaru's and other cars that are known to be good ski cars. The battery is super reliable in the cold. Yes, the range goes down by about 30% which is not even a tiny problem when you have over 300 miles of range to begin with. Every gas car I've ever had lost about 20% in the extreme cold due to having to idle them extensively to get them warm enough to melt ice. The Tesla blows warm air in under 60 seconds without having to start an engine! I could never go back to gas cars.

[@blppt]

I always am amazed whenever I see these teardowns of all the parts which are either moving and/or subject to wear, that we ever got these contraptions to a level that is pretty darned reliable. People may dislike the electrics, but they are so much simpler than ICEs nowadays, they should be inherently far more reliable once manufacturing catches up.

When I first got it I read about the water ingestion issue, and that owners were drilling small drain holes in their intercoolers to prevent it. I instead replaced the anemic little OEM CAC with a much larger Full Race model, and haven't had any problems, even here in humid Florida. My engine has upgraded Full Race turbos that are a little larger than stock, and a moderate tune that makes 435HP / 456 lb.ft. of torque. So far I haven't seen the dreaded cam phaser problem, and the truck is a lot of fun to drive. The DI system is causing carbon buildup I'm sure, and if I keep the truck I'll have to break down and decarbonize it at some point.

MST block to back exhaust system, Steeda cold air intake, manifold spacer and intercooler, Boomba catch can and adjustable bov and a tune for 91 and 93 octane. Conservatively tuned to 320hp. Just my opinion, what kills these motors is cheap 87 and lack of a catch can. The cooling jacket problem only manifests once the engine gets super dirty and hot. Regular coolant flush, minimal oil consumption from turbo blowby from adding a catch can and quality fuel will save your 2.0 ecoboost and let you dial up the power with minimal risk.

[@backlineguy]

dude...your knowledge is astounding!

[@alistairshanks5099]

from an engineering perspective, I think the engines are well-put together and there was no adverse wear or marks on any bearings so oil pressure was not a problem. There were no signs of a water hydraulic lock. As you say the engine was burning oil and this is a problem with direct injected engines used in passenger vehicles and that includes light diesel. It is because they are making pistons smaller and lighter with virtually no skirt and the rings thinner to reduce friction so they can get gains in RPM spool up and fuel consumption/ emissions. The bits they pared back are what stopped combustion gasses getting past the rings and into the crankcase so when this happens the rings get fouled which then lets oil get up into the combustion area which makes the carbon build-up worse. many engines use special bore coatings now that don't always bed in properly depending on how they are first driven. All this tech came from racing engines but street cars are not for racing, They deal with far more cold running and over-fueling conditions that racing engines don't get. These types of gas engines run higher compression ratios as well which also stress the pistons and rings. Not long ago this engine would have been a state-of-the-art racing engine. We are making engines smaller to meet emission standards but then extracting every ounce of power from them which means they are highly stressed. The less stressed an engine is the longer it lasts.

A very useful video man. But 2 things you'll have to correct for the future. The vacuum pump doesn't compress air anywhere towards any outlet, it only sucks air from the vacuum hoses creating vacuum in them and effortlessly sends it into the cylinder head cover from where it goes either to the PCV's breather or the PCV's intake manifold valve. The other thing is that the turbocharger assembly is made out of a turbine which by definition is a series of blades being driven by a fluid while the other series of blades at the other end has the role of compressing air so it's called a compressor. No combustion engine has only turbines, they would be meaningless. One's a compressor, the other's the turbine which drives the compressor. All the best!
