If you go with this approach, use this. It's designed for this kind of repair. http://www.permatex.com/products/Aut...ead_Repair.htm

My father has used this successfully on head bolts before and I have used on a pan bolt (granted not much torque on a pan bolt).

You have got to be kidding me, no way would I trust this stuff. May last 2 or 3 starts, after enough temp cycles if you can even keep it running that long it will crumble.

It's been 3 years on my father's head bolt and no issues. Like Excalibur, he figured he'd give it a shot and if it didn't work he could go with the coil/insert. Although it's in an iron block/head flathead - not sure what the torque spec was for his heads.

Not sure whether you actually looked at how the stuff works, but here's the crib notes: You spread it around in the hole, put release agent on the bolt, run it down in the hole and it fills any damaged area and forms "new" threads in those areas. Then you take the bolt out and let it harden. It hardens to the equivalent of Grade 5. It's good to 300 degrees. If you have a decent amount of good thread left, this might actually be a solution worth trying.

Anyway, just trying to throw out an alternative.
