Well, I did it put my turbo in that is, now I have smoke lots of it. A little back round first. New rebuilt turbo, only took it out once for a short drive, no boost, drove real slow, never went above 3500rpm or 1/4 throttle. This is a new rebuild had it worked on buy Innovative Turbo, full rebuild + turbine and shaft. I Took it back a part and there's oil in the turbo manly the exhaust side but a little in the charge pipe to. The only thing I did is when I put the turbo on was the oil return wasn't in the right place so I rotated the cartridge so the return was facing down. Could rotating it damage the seals? Also the large hole is the oil return port right? Any ideals?
