Strange smoking '94 Bonneville
I have a '94 Bonneville, non-supercharged, that runs great with 183K miles on it. However, I just noticed the other day that, after running for 5 or so minutes, white smoke starts coming out the exhaust. My first thought was a cracked head or gasket and, upon warming up, it started sucking antifreeze. However, in the last 2800 miles the coolant level has not changed. Also, it doesn't smell like burned antifreeze; it'* more an oily smell, but it'* white smoke, not blue.
I guess it could be bad rings but A) it runs great with plenty of power and B) Wouldn't it smoke from start up and be more blue?
My question: is there something else that could be being sucked through a vacuum line into the engine? (like tranny fluid from turbo 350'* with a bad vacuum modulator or ps fluid from Toyota pickups)
I haven't had this car for long and I hate to think it'* dying on me; anybody have any ideas? Thanks.
