Camoit, I have had cars with blown head gaskets, but this one I'm not sure. I know the water level is fine and there is no chocolate coating in the oil. The white smoke is not thick, it's kinda light and it smells like emission problems. Like I said, there are vacuum hoses disconnect and plugged off?? I don't know what that person was thinking about or doing. The spark plugs are even inside of a adapter, why I don't know. lol
