Since I broke a stud off in my intake manifold. I got the stud out. can I fill the hole with JB weld and tap and helicoil it. will it be strong enuff. to handle the intake manifold torque and heat????? Im at my last chance. beofre I havnr to change all my heads or get a new motor. its bad please help???

 

You should be fine with the JB Weld. Just make sure the area is clean and you allow it to fully cure before putting it to use. Is this on the plastic intake on the Vortec's?

 

The damage is on the back of the cylinder head. Not alot boke off but i completly covered the broken area in jb weld let it cure for 24 hours and now Im wondering if I should just fill the entire cylinder head bolt hole with jb weld and then just tap and helicoil that. its would probably be great ill throw a picture up
