before my exhaust used to be purple from oil burning when i reved the engine. now when i rev the engine the exhaust is white.its not really purple anymore. i have a feeling this is coolant. what is the mostly likely cause? who else has experienced this? i need some info. possibly thinking about selling car.

 

i am really no expert but maybee a head gasket?

one more thing my throttle was sticking so i sprayed carb cleaner on and there was like a puddle layin on the manifold could this have make white smoke? i also sprayed some in the carb.

 

definitly sounds like a head gasket to me. White smoke is coolent getting into the combustion chamber.
Check your oil, if it looks like a milk shake then chances are you blew a head gasket.
