Unfortunately, it’s not that simple: Ford cautions against cleaning the intake valves, as doing so could cause damage to turbines, bearings, and seals. But a mechanic should be able to clean them up, right? ![]() The process of direct fuel injection can also cause excess carbon to build up on the EcoBoost’s intake valves. Image source Carbon Buildup on Intake Valves of Ecoboost Engines If the engine backfires, loses power, or you notice it rattling while idle, your EcoBoost may have a bad timing chain. If you’re in the market for a used vehicle with Ecoboost, there are a few signs you can keep an eye out for.

One Ecoboost owner, f150ecoboost mentioned that “If I had only known all of this years ago when I bought the truck new, I would have 1) Changed my oil with greater frequency, 2) used heavier oil, and 3) monitored my oil level and smell much more proactively.” Sounds great, right? Unfortunately, this means that the engine’s oil has to work overtime, which can wear out the timing chain and cause it to stretch. The engine is “turbocharged,” meaning that air and fuel are directly forced into it, producing more power. The timing chain is an integral part of most engines – and one EcoBoost owners have particular trouble with. The Most Common Ford Ecoboost Problem: Faulty Engine Timing Chains Read on to learn about the common issues drivers have found with EcoBoost engines, and how to spot them.
