my exhaust at the turbo blows oil under heavy acceleration.Could the actuator be stuck open and how do I check it? The shaft spins good and there's no play.
If your loosing oil through the turbo the seals/ bearing are bad. The actuator just allows exhaust to by pass the turbine.
are there any threads on how to rebuild them?
I don't think so.
I had a PDF file on them but I think it's stuck on my laptop with a bad power supply.
I sent it to a few people though, maybe someone I sent it to will read this and send it to ya.
Where are you located?
I just found it at work.
PM me your email and I'll send ya the PDF.
It's for a k26 but internally they are the same.
