So...it seems that at some point in time someone managed to strip three of the four bolt holes on the outside corners of my valve cover (the smaller bolts, not the the big ones that go in the center).

I'm looking to buy a Helicoil kit to fix it, but was wondering if anyone knows the thread pitch for the bolts in question? Unfortunately, I don't have access to a thread pitch gauge.

Thanks!

Thanks! If you can't get it, it's not a problem. If it comes to it, my father has access to a thread pitch gauge at work. I just figured someone around here would know since that aluminum is so soft I'm afraid to stare real hard at it ;)

It doesn't help that the boneheads at the dealership probably used air tools to torque the valve cover bolts down. :(
