as i was tightening down my thermostat housing to the intake manifold, it cracked on the front of the intake bolt hole, just a hair line crack, i didnt even have the head of the bolt touching the intake, so i dont know why it cracked. is it going to be fine, or should i buy a new intake manifold? someone told me i could jb weld it, and it would be fine... is that true?

 

This is just an excuse to get a performence manifold and runners if you ask me

 

thats what i was thinking, big bore intake, runners, and plenum, but not for my puny 305 seriously though, what should i do?

 

jb weld a layer over it to make sure its sealed. then u will be fine.

i jb welded my fuel line to my tbi and it worked..

but we're not gonna go into details their.

 

JB Weld would work good.
