water leak of of head bolt....

[felskee]

well after i just replaced the intake manifold for the 3rd time. i started it up with thermostat in and it stayed cool. then i ran it again and it jumped to 260 and then the leak started at the rear head bolt. and its leaking a good amount of water. heads are months new. so then we took out the thermo and it runs cool... i have a 1999 2 dr 5.7 with a brand new 2 core rad. sooo im pretty tired of the process of these repairs. would blue devil head gasket sealent work?

were your intake gaskets oriented properly. Sounds like they are not.

 

[felskee]

like placed the right way?

yeah. I would think that would be an issue for overheating and maybe either cracked a head or gasket. Or perhaps the head gasket was damaged during install. Is the correct coolant and mixture is there as well?

we were using straight hose water to test it.
