Ok boys, ive been fighting this smoking thing for the last month or two, and its making me crazy. Ive got white/grey smoke at idle from the exhaust. My mechanic ran every test he can run with his scanner and everything comes back with a passing grade. It seems i may be loosing a very slight bit of coolant from the bottle. I noticed last night, im going to keep a close eye on it now, just dont drive it enough. So if im thinking right, is it possible that coolant could be getting burnt through exhaust? I dont know but the smoke smells normal to me and im not having any other issues and everything checked out, so what do you think?
