got a 7.3 idi changed the antifreeze went about 60 miles then the overflow tank got a crack in it and antifreeze was comming out changed the tank put more coolant in it and cranked it up thermostat opened added more coolant drove it down the road let it sit checked fluid it was good cranked it up drove it again overflow tank was overflowing and it was smoking white out the passenger side exhaust looks like steam and smells like antifreeze no oil in water no water in oil what yall think it is head, head gagket or ????? and when it cooled down this time it was a little low on coolant??? cranked it up cold without the radiator cap on and water flows out the hole (alot) put the cap on and it builds pressure (cold)

 

Sounds like a headgasket. They can blow and only let coolant into the combustion chamber without mixing coolant and oil. I'd becareful about running it, if it sits and you try to crank it, coolant could leak into the cylinder and hydrolock it. The starter is strong enough to break internal engine parts.

 

Sounds about right. I worked with a guy and he had one that did the same thing. It was about a 92-93 if I remember correctly
