[QUOTE="TexSavage, post: 1550402, member: 6245"] Well not sure if this helps, but I'll relay what my brother and I did with the same kind of situation only on a larger scale. We had a 6 cylinder Cat engine in a Stiger tractor we had to overhaul. One of the head bolts stripped out somehow during disassembly. We first cleaned the hole in the block thoroughly and degreased it twice. Did the same thing to the bolt. We then mixed up JB Weld, filled the hole with the JB Weld, greased up the bolt so the JB Weld would not stick to the threads and tightened it down. We wiped up all excess JB Weld as it oozed out making sure the bottom of the bolt stayed clear of any contact with the JB Weld. Of course we also applied a little grease on it as a safety. We then let it set until hardened and then removed the bolt. We then allowed it to cure for 24 hours. After that we mounted the head and proceeded to tighten the bolt to about 150 Foot Pounds and never looked back. Ran that old tractor for about three years after that with no issues and sold it when we left farming. I know it was still in use several years later. Narry a problem. Now, that was one option, our second was a heli-coil but we were a ways from one so help JB Weld. Key was making sure parts were clean and no grease inside the hole. [/QUOTE]
