Interesting. Thanks for posting your videos.

So do you recommend not letting the truck idle before driving it, especially when cold out? Can this be cured with a reprogramming so the engine doesn't over fuel?

That is interesting and the more I think about it I have another question for the OP. With the head - do you replace all of it - the cams, valves, phasers, etc? Or is it the bare head and you reinstall the rest of the valvetrain components?

Only reason I ask is cause if you replace the whole thing, it could be tolerances or bad phasers that are either allowing too much blowby or lack of phaser control leading to not enough reversion.

That was the "Oh, crap" part.

So the video said "not just eco engines". Wonder what else is going up there on the gasser side. With as many as are on the road, I can understand some failures, but this still seems like a small percent. We need more info I think

Seafoam and other detergents additives do not cause damage to turbos, DI engine or not. I've used it for years on various vehicles. Some DI, some not DI. Some turbocharged, some not. Never once had a turbo issue with any of those vehicles.

If detergent loaded Top Tier gas doesn't clean the back of the valves, why would SeaFoam do so?

You sir, are awesome. I don't own an ecoboost for this very reason, but thank you for the video. It's extremely helpful getting insight from someone who works at Ford.

Any insight on the 5.0 other than cylinder distortion?

Oh I didn't mean to insinuate that SeaFoam worked fantastically well or it solved the issues. My little brother has a MazdaSpeed 3 (DI turbo car) and I've done it on his car 2 or 3 times now. Those guys swear by it and claim it works great. No concrete proof though of course

I only meant to speak to what was said about it ruining or hurting turbos. I have used it on many turbo engines both DI and regular EFI and have never heard of or seen it hurt a turbo. Just my experience.
