Why Ford EcoBoost Engines Fail Demonstration

Understanding the EcoBoost Engine

In earlier articles we have learned more or less in piecemeal fashion the problems often faced with a vehicle powered by the EcoBoost engine. More specifically articles on why 4-cylinder EcoBoost engines are failing; Why some EcoBoost owners are getting the wrong part; and, an important EcoBoost upgrade recommendation.

Today, however, we will discover what basically goes into making an EcoBoost engine with the teardown of a 2016 Ford Focus ST, that reportedly had been subjected to water intrusion from the PCV catch can and led to the totaling the vehicle.

The Value of This Teardown Video

The value of this teardown video from the SpeedKar99 YouTube channel is that it provides in just under 18 minutes all of the components of the EcoBoost engine with discussion of its problem areas. This is very important in that is informative toward helping the Ford owner develop a good idea of its components and understand what his or her mechanic is talking about when their vehicle is in the garage for an engine repair.

In the video you will see a teardown revealing the main components with some discussion of its construction that includes, but is not limited to:

• The Dual VVT valve train
• The cylinder head, exhaust manifold and intake components
• The direct injection system
• The turbocharger
• The cylinder block with its lubrication and cooling system
• The crankshaft and its balancer assembly

But of special importance are the bits of discussion the video host provides in a quick and easily understood manner where the trouble areas lie and why the engine is infamous for being an oil burner and how the main pitfall of a direct injection system is the firing of fuel directly into the cylinders rather than routing through the intake side of the intake valves into the cylinders.

That all said and done, here is a video well-worth watching and learning from:
