Headgasket....

 

deffinitly head gasket, Give it a leak down test, to see whats going on

 

White smoke generally means that you are burning coolant.

You headgasket is probably shot, but it could be a few other things (ie warped head, improperly torqued head bolts, stretched head bolts, gouged deck, etc.)

Did you recently do a re-build?
