I bought a T3/t4 50trim .63ar turbo from a friend of mine, and i've had it on the car for a few months now and realized i have a good amount of oil in my intercooler piping. So i decited to take the turbo apart. I found 2 things that are missing on the compressor side, i found no seal and no thrust spring on the back plate. Could that be the reason why i have oil in my intercooler piping?
that star looking thing is the thrust spring which was missing and i added it and it was missing that Big O ring that seals the compressor. 2nd pic number 11.
