My turbo on my 1994 Volvo 940 started smoking.. The turbo was aftermarket & only about three years old. I used rotella t6 almost exclusively with the exception of a couple oil changes of PU 5w40.I changed the oil every 4000miles.The compressor side thrust washer and bearing/bushing look excellent! But the exhaust bearing and seal are destroyed.. I thought I was cooling the turbo properly after a high temp run.. maybe I should rethink that? Or should I rethink my oil?
