Ecoboost has me scratching my head pretty hard!

Here is what i have come up with, I pulled that intercooler off... not very much moisture, however, there is a good amount of oil.

I'm kind of on the edge of condeming the turbo on bank 2...
Air charge tube for bank 1 turbo is dry (very minimal oil coating as you would expect)

But the air charge hose for bank 2 has a good bit of oil! Probably where it is all coming from.

I am betting from how it feels driving (good under low boost situations, hesitates under higher boost) that we have a turbo failing. And definately the oil seals around the turbine bearing going bad.

Once again i know to expect some oil, thats just the nature of the turbo...
I would really rather not send this guy to the dealer, but i feel i may have to.



On another note, i did a ethanol content test... right around 10%. God knows where he gets his fuel, and i already gave him the Top Tier talk with the direct injection engines.


going slightly crazy here! luckily the customer is a cool dude and understanding about the situation!

Turbo failure certainly isn't uncommon for these engines,but I would expect to see more than misfire codes if this was the case.
Is the oil in the charge air cooler a dark color ? Or more the color of coffee with cream in it?

Edit: have you tried test driving the truck after cleaning the charge air cooler?

Can you post a screen shot or scanner movie of fuel trims and 02s of when the failure occurs ?

Thanks for all the respones and advice guys, it is much appreciated.

Customer didn't want to go much farther than a few hours of diag time. I think he's going to play the stupid card and trade it in on a newer truck
