Ok, have it your way; here is 17 pages worth of 3.5 carbon valve problems on the 3.5 Ecoboost

More reading.

There's more........A lot more.......

BTW, EGR has nothing to do with DI carbon issues. (Or next to nothing for those of you that want to split hairs.)

I never said there is zero carbon buildup on non EGR DI engines. Even port injected valves will have some carbon buildup on them over time. I said it is not a major issue or will cause engine failure like the DI engines with EGR. The soot from the exhaust gasses being re-introduced into the intake on a direct injected engine compounds this problem making it a major engine issue leading to engine failure.

As of today, have never heard of carbon buildup causing engine failures on a 3.5L Ecoboost or any other sluggish condition that a few minutes of "driving it like you stole it" won't fix like on port injected engines.

The engine won't fail. What will happen is your engine starts loosing power, going to be hard to start, and gets poor fuel economy from carbon build-up.

Bore scope of an Ecoboost engine with 15K on it.

The reality is that while the new EcoBoost is an impressive engine, carbon buildup will happen and for now, the only fix seems to be replacing the cylinder heads.

The OP had a turbo go out x2. My point to the OP is this: This engine has some congenital problems; BUT turbo's isn't one of them UNLESS someone has be dumping chemicals in the intake trying to clean up the valve carbon problems. If he or anybody else has been doing this your likely to have turbo problems.

All DI engines have this problem. It's not exclusive to the Ecoboost. It has nothing to do with EGR. (I don't even know why EGR was brought up?) It has everything to do with valve overlap and flow reversion.

Troy is right. Ford is going to solve this whole debacle once and for all with the 17 model. How? By designing a whole new fuel system with a double set of injectors. This is the proper way of fixing the problem. This is a first with DI as far as I know? The tuners are going to go ape shirt over this 2 injector deal. With a double set of injectors they now will be able to run duel fuel, E85 or even straight meth in this engine. They are going to love this whole deal!

I suggested this way to fix this problem way back when on this very forum. I wonder if I should file for compensation from Ford for my recommendation? :B
