In most cases, the white smoke is an indicator of coolant finding a way into the combustion chamber. This could happen through a damaged head gasket or a crack in the cylinder head or engine block. Most of the time, this would also be followed by milky oil or overheating problems. However, it could also be a problem with the EGR system, or an extremely rich fuel trim. The best thing to do is have a professional mobile mechanic complete a smoke coming from exhaust inspection, so they can pinpoint the source of your issues and recommend a repair.
