Why does a lot of white smoke emit at idle after a hard revving the engine?

You may have a blown head gasket. The white smoke may actually

be steam from coolant leaking into the combustion chambers. If your

car is using a lot of water, this would back up the blown head

gasket theory.

White smoke is coolant and black smoke is oil. I agree that this

is likely a problem with your head gasket.
