76 280z white smoke, slight temp fluctuation.

[Indey]

Alright I have a 76 280z stock motor in it, the whole car is stock. Now, sometimes the temperature will rise above normal a bit, but come right back down, and white smoke will be coming from the exhaust. The white smoke typically shows up more often on deceleration. Any ideas?

Typically white smoke is a blown head gasket, check your coolant. Has it gone down. Or better do a compression test. Try smelling the smoke next time. If it smells sweet its coolant, burnt is oil(oil should be bluish), and gas...smells like gas(should be black).
