White smoke is antifreeze, intake or headgasket.
White smoke will come out of a vehicle's exhaust system when the engine is cold. This is because of condensation build up in the engine and exhaust. The white smoke should go away after several minutes of idling. If you engine is always blowing white smoke, regardless of temperature, then it might be burning oil. Check the levels of your engine oil and your transmission fluid (if you have an automatic) and have the engine compression checked for blow-by.
Water is in your engine. Check intake and head gaskets.
Could be getting into engine. Check tailpipe emissions for white smoke.
Antifreeze leak, failed head/headgasket? Have it checked for codes.
