white smoke could just mean your burning oil. bad head gasket will either show oil in your coolant or coolant in your oil. burning oil enough to turn your exhaust white means you have very worn out piston rings. so either way, im sorry to say its not good...

oil burning is blue smoke, fuel mixture rich is black smoke, white is steam, and means that coolant is getting into combustion chamber.
