I just took off the turbo exhaust housing was clean, turbo was nice and tight..... took the cover off the cold side and the cover had oil in the bottom took the wheel off and oil was behind it and and the bolts for the back off the cover had oil on it wish I had a camera to take pics at the time but used the wife's yesterday since mine is broken....
Turbo looks fairly new only thing I can say maybe is the brass looking bushing that seals the rear part of the cold cover has grooves cut in the aluminum like it was scraping. Owner said he bought the turbo off here and it was suppose to be ported which I didn't see anything. Here the link to the car I got.
Inlet tube had a tiny bit of oil right at the turbo from what I can see and feel.
