My car had bad boost creep, so i ordered an o2 dump. So i take off the manifold, unbolt my downpipe take off the o2, put the o2 on, put the manifold and downpipe back on, easy enough done deal. Ok heres where shit hits the fan:
Keep in my mind my car worked perfectly before i replaced the o2, it has a fresh 14b turbo, the motor is in good shape (150 comp across).

i did nothing except replace the ####ing o2 housing with that new 02, start the car, drive for like 10 seconds, WHITE SMOKE EVERYWHERE, were talking billowing clouds, well i try and boost into it and the turbo spools fine a solid 16psi, come back to my house pop the hood, oil everywhere all over the front of the engine, turbo, o2 housing and downpipe, AND theres also oil pouring out the exhuast as in the back of the freakin car out the muffler.

I examine shit to see if i can find out what the hell happened, clean the oil off and look for leaks somewhere. I start the car and examine things to see if i can then fine out where its leaking. Again its leaking all over the place, from the turbo compressor housing, from the o2 housing, all over the place

I check the oil feed and return line and ironically enough theres no leaks with either, So im just like WTF???? Good motor, fresh turbo, where the hell is this oil coming from, and out the exhuast?? AAAAGGGHHHHHH :mad:
 
Did you use anti-seize compount on nuts, O2, etc . . .? If so, you may have gone a little crazy with it and the white smoke is just excess burning off.

Also . . . there might have been some kind of coating one your dump to keep it from corroding while sitting on a shelf. Kind of an oily film?
 
I didnt use any antisieze or rtv on anything, the dump was coated inside and out with high temp paint bullshit. i expected that stuff to burnoff and smoke for a while, but i still have OIL everywhere and pouring out the tailpipe
 
I wonder how possible it is that the 14B is the culprit? If oil is flying into your exhaust, that would mean you've either got a ton of blowby or the turbo is blown up. Maybe I'm missing something but I can't think of anything else. So my guess is bad turbo and a distant bet on fried piston rings. Even if the new o2 was bad, I don't see how it could cause what you describe.
 
Yeah im also thinking turbo now after driving it again, power comes on late and it only smokes when boosted.

Off the subject but would i test good compression with fried piston rings?
