[QUOTE="dthompson, post: 913381, member: 4901"] Ok here's the deal. 02 7.3. Bought it guy said it had a blown head gasket. Well there was fuel in the coolant, and he said it was pushing coolant on him when he parked it. I started with injector cups and o-rings. They came out easy and some even came out with the injector. I thought good, this is the problem. Now it can idle and drive around town and it's fine. The minute you try to drive it down the highway the temperature goes up and it starts puking. As soon as you slow down, the temp comes back down pretty quick. Also the heater doesn't blow warm. I'm curious as to if it's pushing cause it is hot or pushing coolant because of the head gasket. Any chance water isn't circulating, making it warm and start puking? Also seems like the coolant system is holding pressure. Hadn't drove the truck for 5 or 6 hours and when I loosed the cap it had a small amount of pressure still? I am just looking at all possibilities. Any Ideas? [/QUOTE]
