I have spent some time scowering the forums and am getting a little baffled and off-track. I have a 2001 9-5 (2.3l base wagon) and am starting to get the puff of bluish smoke upon startup. Seeing as this has not been going on very long and the performance of the car hasn't changed, I was wanting to try to rebuild the turbo. Before I take the turbo off and drain the oil and coolant I wanted to check to see if a rebuild was possible or if I just had to drop the cash on a new turbo. Is there a way to check the turbo's condition without removing it or draining the oil/coolant? I am sorry if this information has been posted already; I was not able to find what I was looking for in my search. Thanks everyone!
