Well, i replaced my timing chain last night. While torqing the cam cover I somehow stripped out the LAST bolt. 7.2 ft lbs and it stripped. This is a hand me down bike and the head has been apart at least twice. I didn't do it, but I get to fix it.

Anybody ever put a helicoil in one?

I'm getting ready to try.

I's no biggy, same as any other install of a heli-coil...Drill, tap, insert and away you go... Just be careful to make sure it is straight and only remove material to the depth of the original hole... Double check the length of the bolt when you install the heli-coil as the bolts get pretty close to the bottom of the hole originally so the little insertion iece of steel in the center of the heli-coil may not get deep enough and you may have to trim the cap bolt slightly...

What torque wrench are you using? What range does it cover? You realize that if you use one that has a large range and are using it at the bottom of it's range it can be off by a fair amount...I like to use inch pound units as 7.2ft/lb is a pretty light torque...

drill or tap trick that i use is that i drill a piece of bar stock to use as a guide for a drill or a tap held flat on the surface to be done. won't work on curved areas though. how ever i have a small v block drilled on center to work on curved areas. just thinking.
