wondering why we're not hearing of intake valves coking up in turbo diesels, they've been DI forever. with the number of miles driven by semi trucks you'd think it would be an annual event.IDK....I fill up at Sams Club (not top tier) most times and MTE is usually right around 500 in 2.0 EcoBoost. I suppose carbon is going to encapsulate my valves and need walnut blasting by 75k miles?? Be interested to know if any owners of higher milage Mavericks with Ecoboost have noticed any issues with carbon buildup on valves(especially ones that don't use top tier gas all the time)?? Is this still an issue with this particular Direct Inject engine??
