Only thing I see with the turbo, is that one of the impellar blades on the intake side has some of the coating flaked off. It almost looks like ceramic underneath. I always thught these impellars were cast aluminum or iron, so I dont know what the coating is. I dont see oil anywhere. I did just block off the PCV system, cause all its doing is drawing air through the block, through the valve cover breathers and acting as a vacuum leak. My vacuum at idle has gone from 15in. to 18-10 after doing this, and it runs ALOT better.
