smoke turbo related?

[turboaddict]

alright my car suddenly started smoking. its oil smoke. the car only smokes when not in boost. even while driving under vacuum (i.e. turbos spooling but not making positive pressure) its smoke free until you decel or idle. hold it at 1500rpm no smoke. i just have trouble believing that a bad turbo seal would act this way. even under full throttle 14psi no smoke. the car has virtually no blow by and has 100psi across the board. no oil in intercooler tubes or on plugs. thanks for your help guys its just every turbo ive seen go out doesnt act this way and i want to go racing this friday!

valve seals

again no sign on the plugs, and when i say smoke i mean smoke !!! not just like a old 3.0l but like a smoke screen. i would think with the amount of oil coating the exhuast pipe that some would show up on the plugs if it were valve seals. either way ill pull the valve cover tomorrow and rule out the valve seals.

Believe it. When spinning the turbo is still able to seal, when it slows down is when the leaking starts...

glhsken is right because oil pressure pushes the seals out

If it takes a couple minutes after starting it up on a cold engine, I would say that it is leaking oil through the seal on the turbine side. Otherwise the aforementiond problem is where I would place my bet.
