Message	First you have to confirm it's definitely and not grey or blue... White smoke (after car is warm) is due to water/coolant in the combustion. I assume its an auto (standard) it could be: Transmission fluid may be entering the intake manifold through vacuum modulator. Cylinder head gasket(s) may be bad. Cylinder head(s) may be warped or cracked. The engine block may be cracked. check/replace vacuum modulator, it's going to be your easiest and cheapest option, the rest are expensive. if not the problem get a compression test, that should show up if head problem, also check for cream in the water and oil. You can also check for CO2 in the water, you can get kits to do this.
