I have a 1997 buick lesabre with the 3.8 v6 (k) engine. It ran hot the other day and I could see white smoke on acceleration, but not everytime I accelerated. The oil does not have any water in it. But Water is getting on top of my pistions. I removed the plastic cover (throttle body?) from off the top of the intake. The top of the intake is full of water. Is this normal? Could it be head gaskets or intake gaskets? I am puzzled as to why water would be in this plastic cover. The acceleration linkage and air cleaner attaches to this cover. Any help you guys can give will be appreciated.
