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. |

QUOTE(aharder @ May 10 2021, 05:10 PM)  Belmetric has a 10 x 8 for 3.99ea No get the M9 x M8, the M10X8 would be the last ditch Hail Mary. If you tap for M9 (or helicoil) a regular timesert will no longer work, you would have to now use a "Bigsert"...so a whole different timesert kit. You only have so much meat to work with...so you can only go so far oversize. |
