I am considering an overhaul of the T4 turbo on my R. It seems like it is easy to do but a real bear to take it out. I am pulling the cylinder head off my R and it seems like a good time to do it while the head in in the machine shop. I have not had any problems with it but I found a lot of oil in the intake and charge pipes. This could be only because the oil separator was clogged at the crankcase drain.
The car has 107k miles on it. Is it worth it to rebuild the turbo just because I can? And does anyone have a trusted source for a rebuild kit?
