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.

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.

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.

[@brianm.4243]

@@speedkar99 The idea of direct injection turbo charged engines scare me. 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.

[@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.

@@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]

[@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!!

First of all, my hats off to you for doing a excellent job on your videos. Great breakdown and very thorough on your description per component. Secondly after seeing such a monstrosity of a 4 cylinder, gave me such a headache from trying to understand the explanation of over engineered failures (i mean flaws) that I now feel perfectly content with my old school engines of yesteryear. No matter how much technology you put into these newer vehicles and engines alike, most of them will eventually break down beyond the value point of putting them back on the road.

Great video. Have a 2.3 Eco that failed... was putting coolant in cylinder #2. Motley Crue concert fog behind tailpipe. Head gasket had failed in that area where the grooves are machined in the next gen block. Putting in a new head gasket and a new head with ARP studs and hoping it holds together. We shall see!!!

[@bouffant-girl]

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.

[@know916bound]

@@harrywalker5836 nope. Ford bought into mazda because they couldn't build anything other than a v8 reliably. Mazda was good before ford. And got bad during ford. And got better after they left. The eco-boost is a bad turn based on mazdas L platform. Which mazda took and improved into skyactiv which are solid. While ford still can't improve a damn thing and are struggling to improve off a platform they worked with for years but didn't develop. They only ever threw money and hopes at it.

[@watsisbuttndo829]

Shame they dropped the ball on the cooling system because the bottom end looks extremely solid. Very surprised to see bearing shells on the cam journals as well as that is actually a nod toward being able to repair an engine rather than it being a throwaway. So close yet so far.

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!
