Engine Teardown Shows How Poor Maintenance Killed This Ford EcoBoost

What showed significant damage was the turbocharger, a key piece of the EcoBoost series. Eric wasn't surprised considering the engine was sitting, making it vulnerable to weather.

Another thing you wouldn't want to see was oil in the high-pressure fuel pump. Eric suspected the engine could have a faulty oil system, and the only way to find out was to carry on with the teardown. He could be right because after removing the valve cover, he saw excessive oil with metal flakes. Rusting was also found on the camshaft gears.

Like the 1.0-liter EcoBoost engine Erictore down before, the crank sprocket was not keyed, which, he said, could be a product of cost-cutting measures. The camshafts' conditions and caps were also said to be "not great." The same goes for the two pistons, with one drowning in water and rust.

And yes, rust was one of the main reasons for this engine's demise. However, after a thorough teardown, Eric also discovered oil-related issues. The presenter concluded this could have been caused by poor maintenance and not necessarily by engine design. It is a similar issue to the 2.7-litertwin-turbo EcoBoost V6he tore down weeks ago.
