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
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?
*Damn I hate working on exhaust systems*

exhaust temps exceed 1000 degF.
there's no data on how SOFT the JBWeld epoxy gets at 600degF,either.
It's not going to be as strong as at normal temps.
600degF is porbably where it starts melting or begins to char.
ISTR a tube of goop called 'muffler bandage' that would withstand exhaust
heat,in fact depended on it for it's curing.My tube was thrown out in the
last spring cleaning,or I'd verify and get the exact name.
