Overheated

beauhymel · March 24, 2010

Seems that my wife overheated my truck until it would go no more. I have a 1996 GMC 1500 with the 5.0. After the truck was overheated the known problems are, leaking water pump very very rough idle. It seems to be running on 3-4 cylinders, not enough power to move truck. My question is what to look for? The oil is still clean and looks good antifreeze gone. I think I have at least a blown head gasket, maybe warped/cracked head, or block. I need to know where to look for cracks and any other Ideas. Thanks in advance.

Well I removed the heads and it is worse than I expected. Both heads have cracks. Should I dig more or is this something to expect with an overheated 305. Now I need to go over my options, junk-yard, reman, or new heads. Thanks for any input.

Has anyone used Cylinder Heads International? The website claims to sell 1200 heads/month. Their price seems good, but I would like some feedback from someone that has used them. I checked the block and it is flat. I also checked all visiable surfaces and that looks good. Does this block have any week spots that I should try to check more closely. The cylinders all look good. (as much as I can check with the pistons still in there)Thanks again.
