Default Re: Snapped Rear Mounting Studs (3rd time!)

I had the exact same thing happen with 3 bolts and ended up having to drill & tap new holes into my engine.

I put the bolts in with no other mounting hardware and matched everything up, on the side, and realized that my bolts were a few threads too long to pull everything together tight. I also realized that a torque wrench set to 50~75 in/lbs. is tighter than I had done with my hand (I had been afraid to tighten them too much for fear of stripping/breaking things with my gorilla grip).

Make sure your bolts are the right length (won't bottom-out without pulling everything tightly enough) and a torque wrench is highly recommended!
