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.
  • FINALLY - a tear-down video series from someone who is not only knowledgeable, but knows how to edit so the audience doesn't go to sleep watching someone pull every one of a dozen head cover bolts. Nice - clear, concise, great information, and a fun to watch.
  • I love that you include the personal effects of the whole family in these teardown videos.

    The quality of editing on your video is top notch as it quickly gets to the point without skipping major steps. The voice over is great and clear. All vehicle tech videos should try to match this quality. Thanks!
  • "One thing I like about this engine is a flat bottom pan so when it fails, it sits flat & doesn't fall on your foot" 😂 I love it. Great teardown, thanks!
  • I have no intention of ever trying to dismantle an engine but YOU DID A GREAT JOB OF EXPLAINING! I am so impressed!
  • 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.
  • “Until the oil companies give up and we’re all mandated to drive skateboards”… This is one of the best recaps / summations of a very complex year down and visual explanation of why this engine design ultimately fails. You couldn’t have summed up better sir.

    Actually looks like one of the better designed and built engines I've seen in years. Also it appears FAR easier to work on than many of it's contemporary's. But honestly the direct injection without an intake manifold injector is just a death sentence for all direct injection engines. Great video as always.
  • You have done the best engine tear down video I've ever seen. You know what you're doing and I so appreciate the explainations! I've been in the industry for 45 years and this new school stuff I never got into. Thanks for the explainations and I so appreciate your knowledge. Great Job!!

    Had this engine in my 2017 escape titanium. Liked it a lot. No complaints at all. Great power and torque. Engine was not burning any oil. Car was sold with 186k km on the clock. Good mid grade and premium fuel as well as frequent oil changes (I did it every 5-7k km) and you could easily get 300k km and more.
  • 180k miles on the 2.0L ecoboost in my 2013 Escape. Only service has been spark plugs and oil changes. Occasional smoke on startup but still feels pretty solid!

    This guy = the best. Not much time waste & tons of accurate info. Definitely knows his craft. Thank you, Sir.

    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!!
  • GREAT mechanical review! You have a gift for explaining things in an easy to understand format. Keep up the great work 👍

    Never underestimate what can be done with a toothbrush Edit: Your brother's wardrobe must be empty by now
  • @Aaron-be2pt
    I'm a big fan of watching teardown videos and etc., other people doing repairs - but really, YOU have the formula down pat - you have and amazing cadence and tempo for dismantling engines. You really ride the edge for showing all the components and keeping it simple enough to keep our attention. Awesome video!

    Probably the best engine strip video I have ever seen. 👏👏👏
