Tuner Boost

Here are some videos of ecoboost intake valves through a boroscope showing valve coking at 33,000 miles:

This is app 1/3rd what a GM 3.6DI or a BMW, etc. would have at the same mileage, but still severe enough to cause idle issues and related power & fuel economy degradation.

And those deposits have what affect for most??
MPG? (nope - I've debunked that one handily)
Performance? (negligible or show a before/after dyno run)
Engine longevity? (EB is coming up on 5 and no major widespread issues).
What then?

Come on man, back up your claims! You have built all these engines, you own a speed shop, you see all these problem Ecoboosts. Did it never occur to you to strap one to your dyno and do a before and after? Heck, you own one - strap that bad boy to the dyno before/after? Would be simple to prove your point with 0 effort on your part.

While I do agree Ford is seeing issues with deposits, with over 1 million Ecoboosts of all flavors out on the road some will have issues. Unfortunately we will never know the true #'s - only Ford will).

Ford= Found On Road Dead. Used to mean so, anyhow... LOL.

I have a VW TDI (diesel)- so drive your EB like you stole it now and then. TDI's were (are?) known for soot build-up at EGR/intake.

Don't shortcut the engine oil.

Do it, can see the black soot coming out of the exhaust. oil always 7k full synthetic mobile one with wix filter or K&N

I have a 2004 TDI bought new. Has 233,000 miles on it, still uses no oil between changes and have run it hard since the day we picked it up. Been through 2 turbos and did the PCV mod early, and a clutch (all seem to go through the clutches eventually) but it still is a 43MPG champ!!

The operational characteristics of intake valves gumming up is at idle, and mid engine speeds when it first manifests itself. Holding it at say 3500+ RPM's will relieve some of problem of rough running for a short while. It will return though with a vengence. Usually a tair down soon for related reasons happens. The loss of intake vacuum means hard starting or in worse conditions flooding an no start up at times. The OP will first do spark plugs then Cops ect. An the symptoms come back. Exhaust valve failure is easier to find. They usually crack an burn due to poor seating ( open slightly ) due to wear.

Yeah it was an oddball for sure but us at Ford are all new to this direct injection and turbos and the problems associated with it. I am happy to report to this day the wife report the car runs great with the fix I explain in my Part 2 video, even on these cool 50 degree mornings we have been seeing.

U will experience it with CNG fueled also.

If you have to break down the top end to get it clean makes no since at all!!!!!! i understand carbon going thru turbo fans and messing them up but something has to be easier than doing it yourself or taking it in to get the top end broken down at 38k to get it running great again. i have 38k on mine now, don't get it!!!! i sill want to try seafoam i've always used it never on a DI and would of used it by now if i did not find this post damn you seafoam damn you ford lol

It seems to me warranty should cover it until past environmental parts are past warranty. This isnt a new problem just a newer fuel system/PCV creation. Go back to earlier times an poor fuel caused gummed up intake valves an detonation/pinging. Possibly a better port injection system will win out eventually with lighter aluminum vehicles. I mean why not HP port injection instead of D I for most work / daily to job vehicles. Remember first there is nothing new about it only some telling us it doesnt exist.
