7.3 IDI head gaskets.......

Has anyone every done them? Should I shoot myself now?
I'm loosing coolant and do not see a leak at all....... however coolant / oil is not contaminated at all.

wishfull thinking, I did fill my cooling system with just water wonder if its evaporating?
The one place I get my coolant from was out of stock and I haven't made it back to see if they have more.

Unfortunately there are other reasons for loosing coolent. I've had two motors with porosity in the block, no mixing of fluids, but coolent was being burnt and sent out the exhaust.. Thinking the the problems on the first was head gaskets, we tore the motor apart to not find anything wrong with the gasket. Put the motor back together with new gaskets and a fresh set of heads we had and was still blowing white smoke. Ended up putting in a new motor. Second time it happened on another truck we just bought, we pulled the heads and found nothing wrong with the gaskets on that one either, we just pulled it and put in another motor. I hope this isn't what wrong with yours.

After pressure testing the cooling system I found that once pressure built in the system it was blowing a mist out of a tiny leak in the radiator.

That's great to hear, changing a radiator is a hell of a lot easier than a motor.

The trunk running at idle is fine. Once I rev it to 1500 or so it Shoots out coolant from the back of the head where the head meets the block.

Sorry to hear that, it's a tough project, but not impossible. Make sure you have some strong friends or maybe a cherry picker, that damn head is heavy. What is the truck your working on, a 2wd or 4wd? I may be interested in it.
