Using JB Weld on Exhaust Manifold ?????
 

Has anyone ever used JB Weld on an exhaust manifold?
I am doing some exhaust work and for some reason the studs came out of
the manifold rather than the brass nuts coming off. (I thought that
was strange). Anyhow, I decided to replace the studs and nuts while I
was at it. There are 3 of them. Two worked fine, the 3rd will not
hold in the manifold. Apparently the threads are bad. Changing the
manifold is not an option. However, what if I JB Weld it in? I know
JB Weld is good, but is this too hot for it to work? Has anyone ever
done it?

One other thing. I used some anti-sieze on all threads. What can I
use to remove it before I use the JB Weld (if I do)? I dont think it
will hold good to that stuff. Will carb cleaner remove it?

Thanks

Drill it out and install a helicoil.

JB weld is plastic, what is its melt point, temp limit. Probably to low
for exuast.

I have a tube but haven't used JB Weld. I've used PC70 a lot, and I
patched a little pot with it, then boiled water, forgot and boiled out
all the water, and that continued to work.

They state it's 600deg F.
However, I have no idea how hot a manifold gets (by numerical degrees)
