The white smoke is coolant turning to steam. My 89 Corvette, has developed a serious smoking problem. The car is well maintained, oil changed regularly, and is not driven in the winter, and has only 49 k miles. The problem came out of nowhere, it wasn't a gradual thing. Before I go through the trouble of replacing the valve seals, I figured I would get some advice.
Any advice is appreciated.
The sweet smelling white smoke is coming out of the exhaust and is probably coolant. More than likely, the head gaskets have failed. There is a slight chance of a cracked head.
