Turbo blowing oil into exhaust on 2000 Saab 9-3

I have a 2000 9-3 convertable with the 2.0 185hp engine the turbo is sucking the oil out of the crank case and not returning it but pumping it into exhaust.could it be the return tube is coked up(plugged) and can the seals in the turbo be replaced? ive been a mechanic for 20yrs but never worked on a turbo yet, any info would be much apreciated.

Norman you should drop the header pipe at the turbo and check for oil around the shaft- it may also feel loose indicating the bearing has failed( some looseness is ok). If not check the crankcase hoses to the valve cover, ect for blockage. Good luck! Greg

Greg thanks for the info I removed the header pipe and moved the shaft about 1/4 in total from side to side me thinks its time to replace or rebuild the turbo, how hard are they to rebuild?

The first thing to check when diagnosing an oil consumption issue (I.E oil in exhaust) is if the PCV system has been updated. There is a technical service bulletin that Saab released that addresses excessive oil leaks and oil consumption. If you need help in determining if this update has been performed, call Rempt Motor Company at (253)931-0500 and they will help you determine if it has been updated or not.
