Steam and smoke from the tailpipe. A little steam coming out of the tailpipe is normal, but this is obviously not normal. Thick cumulus clouds that actually affect the local weather. And SMOKE! I'm banned to the non-smokers section of the neighborhood. Bad piston rings, valve seals, head gasket? All of the above? I need to narrow it down before I bring it in. Assuming the worst, how many 00's should I expect to pay to get this fixed? In a way I don't care how much it costs, because I have peace knowing that once I get everything fixed on this car I will park it and never touch it again until I sell it. I've owned many cars in my life, and this one is by far the most unreliable money pit I've ever owned!!! Stay away from these cars! Don't even park next to them, lest they contaminate your car with their festering pustules of volvo-eating bacteria!!! Anyway, thanks for your advice...
