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.
