^^^ also wanted to mention that my turbo didnt whine either while it was burning oil. The turbo is on the way out. I would be glad for you if its just the seal but if you are making that much boost on any turbo I beleiev you said 28psi), you will shorten the life of it.

mine smokes at idle now as well. If you are going to take the motor apart you will see in more depth if there were other problems. Look down inside the manifold and see if its wet with oil. That would signal if its a valve guide or valve guide seal causing part of your smoking problem. Then check the O2 housing and see if its wet in there. That would be your turbo seals. Either way, depending on how many miles you have on that turbo, I would bet that you have more shaft play than what would be "normal".

well the turbo is a 20g-green. i've only got about 600 miles on it now..and the only time it's been to 28 psi was on race gas on the dyno. that was it. shaft play should be minimal, otherwise i hope buschur would cover me...j/k

it depends on how it went bad but it can do any of the following:

-smoke from the turbo
-lots of oil in teh intercooler
-lots of oil in the downpipe and you still have good compression/leakdown numbers
-excessive turbo lag
-noisy turbo
-wheel/housing contact, you'll see the scratches.
