I have a '97 850 turbo wagon with 100K. It has developed a mysterious oil leak which looks like it's coming from the turbo itself. All other area have been taken care of. Indy told me a couple months ago that rear main was fine. I've had a front cam seal replaced, dipstick o-ring, turbo return line gaskets, etc. When I'm up under the car, it looks like there has been oil dripping from the turbo. What could this be? Also, when the car is idling, after about 30 sec. I can rev the engine and I get a puff of blue smoke out the back. Could oil be getting into the turbocharger itself? Any input would be helpful.
