what is it when white smoke come out your exhaust

 

your probly driving an oil eater.

 

^ ya u might wanna think about a rebuild

 

White smoke = Burning coolant
Blue smoke = Burning oil
Black smoke = Running rich

 

white smoke means you might need a new head gasket, and is it just on startup, because if so most engines do when you start up. Also check your oil and if its white or looks like peanut butter then you have coolant mixing with your oil.
