Default Re: Hole in water jacket

I would carefully measure the depth of the hole vs the depth of the stud . Was a helicoil used? You could do a couple things.
One , use a small plug ( like a hardened threaded set screw) on the bottom end near the water jacket and install the plug first . When you install it use jb Marine as it will endure fluids better. Put in threads and end of plug liberally.
Then install stud with the same on the back side of the threads. You can use some other sealer like etc or right stuff in outer threads if you wish.

If you want it rebuilt later a torch on the stud will fix the fix if you know what I mean .
Be methodical and careful. Measure twice cut once !! (So to speak ) .
If you need to cut a few threads of the end of the stud to have enough that’s ok . The alternative option would be to forgo the plug at the back and put a very liberal amount in the hole and end of stud prior to install. The plug I would use is the hex set screw type. Be sure to match threads

Good luck !
