Hi there:

White smoke out of the exhaust usually means that there is coolant getting into the cylinder head, or engine block. The most common cause of this is a blown head gasket. However, in some cases if the PCV valve is damaged, or clogged with excessive carbon build-up, it can cause this issue as well. The best way to determine this however is to have a professional mechanic complete a car is emitting smoke from exhaust inspection; so they can ascertain the precise source of your white smoke issue.
