As title says, I have an exhaust leak because one of my stud holes in the case is stripped and will not hold. Tried loctite red, but didn't hold with tightening. Also, wasn't sure it would hold with the heat. Thought about JB weld but then reconsidered.
I know I can tap to a larger diameter but wondering if others have had a similar issue and what you would recommend. Any guidance would be helpful. Case is for 1971 1.7L. |

I would fix it using a threaded insert like "Helicoil". You wouldn´t have to drill much larger. These things work really well, even adding additional strength because of the slightly larger thread diameter. No worries about heat affecting chemical repairs, too.
