I'm not liking my s50 right now it's leaking oil and coolant from places I can't see and now recently when I start the car I get a billow of blue smoke then it goes away after 2 min, would these symptoms warrant a rebuild? And what should I expect to pay? I can't do the work myself. And what parts will I expect to get replaced, and should be replaced. I have no idea I just want the motor to run healthy with no leaks and have peace of mind that I can go on road trips with it.
