I was reading another older thread on her about someone that used JB Weld on a cracked engine block. They said it worked well on a HOT engine. Someone else said that JB Weld is rated to 600 degrees F. OK, but will it work on an exhaust manifold? I have one of the 3 studs that refuse to thread into the manifold anymore. The stud is new, so the manifold threads are shot. I am not willing to change the whole manifold since I probably wont keep the car too much longer, and the new stud will probably outlast the car. I thought that JB Weld might keep it in there, and after it dries well, I can tighten the nut, (but not real tight).
I have no clue how hot an exhaust manifold gets????? It it over 600F ???
This is a Chevy 307 engine (the olds engine they used). There is no way to drill thru this manifold and use a nut and bolt (some can do this, but not this one because of the shape).
Thanks for all help
