Blown head gasket
There is a tester you can use that screws on the radiator cap and you can pump it up to see if it has a leak down effect in the system.. This wont tell you where its exactly going but tells you if there is a leak in the head or intake gasket.. probably should start with the intake and replace it and see if it does the trick .. if not then tear it down and replace the head gaskets and or check heads for cracks also.. thanks Jerry

a little more info when i took out # 3 plug it had gas on it but i am getting fire thru the plug
little more info i found that when i crank it and let it run it blows white smoke out the tailpipe. with a steady stream of water. i can't tell if it's the intake gasket or a head gasket
just another thought if it has a EGR valve replace it ... Jerry
if that has a coil pack... remove one wire at a time and note how the engine idles.... i suspect you will find cyclinder not getting a spark
have u checked for intake manifold vacuum leaks? have the injectors been cleaned/flow tested? any trouble codes or a check/service engine soon light?
