Question about 2004 Saab 9-3
Likely a turbo impeller shaft seal failure. If you want to confirm, pull the inlet to the charge cooler (driver's side, behind bumper cover 7mm clamp) If oil drips out you have a bad shaft seal in the turbo, if not I would perform a leak down test to insure rings are sealing adequately. (not a compression test) If this checks out, I would suspect valve seals. (not likely although it has happened). Head gasket failures are not typically as catastrophically smokey as you have described your car to be, unless the leak is also compressing the cooling system. I buy these cars all the time with this issue, only to replace the turbo and sell them for thousands more. Just my 2 cents...

Sounds like it's time for a compression check. The head or gasket could be blown, and this test will confirm or deny this fact. Your smoke/steam and the oily residue are pretty good clues...accordianman
