Stripped header threads

I have an exhaust leak from my header due to the inner threads of the engine block hole being stripped and the header nut cant tighten. A mechanic suggested trying jb welding the bolt in the hole. Any other suggestions?

All of those bolts come out. If you want to REALLY fix it your best option is to take the manifold off, soak soak soak the bolt with panther piss and take it out. If the inner thread are messed up you will need to retap. But if you are looking to just make it seal you could use JB Weld, just hope you never have to take it back off again.

And they would just put the jb weld in the bolt hole not as a sealant.

I wouldn't use JB weld. Do it right, like Blackbalts said and avoid future headaches (for you and a potential future owner).

Real fix would be to helicoil. Take the studs out, drill and bottom tap the holes, screw in your helicoils, let treadlock cure for a few hours then you have a real fix.

Are helicoils rated for that kind of temp though?

The mechanic said jb weld is really the only way to go.

They're stainless steel, melting point is like 1730F higher than aluminum and about 550F higher than a cast iron manifold. I think it will take the heat okay.

JBweld is a short term solution for a lazy mechanic.
