not to sure if its anything to be worry'ed about about but.

I get a crap load of white smoke that has a strange smell cant really say what it smells like. If i rev the engine even more smoke a lot of it. buBt after driving to the end of the street. The smoke goes away when the car heats up it seems.
note it does not smoke all of the time when i start
