Head bolt stripping at 10 lbs/sf?
https://imgur.com/a/iFO3G1vThis is a situation I've been in many a time. How do you know when you're stripping threads torqing bolts? Book calls for 17-22 lb/sf and it has stayed at about 10 for a bit too long for my comfort. There's always part of me that says 'just keep going, it's made to handle over 22lb/ft. You're almost there, don't quit!' and I don't trust that voice 100%
It's definitely getting stuck too early. Strange. These long bolts have a long way down to the threaded hole. You'd think it'd be pretty difficult to strip the threads. Well I would.
Been looking online for some type of tap extension. Found individual long taps but very expensive. Trying to avoid having to take it all apart again. And you gotta get new gaskets each time right? Well at least if you don't want to take chance of any resulting leaks right? Or is the possibility not THAT likely? I JUST put in a new gasket set.
Anyway, unless anyone comes up with a better plan I think I'll try retapping the hole with the bolts themselves, different ones to avoid possibility one catches the thread in hole wrong. Maybe torch the bolt first, oil, then rethread? I'll say I turned the bolt a good few times with the torque wrench @ 10 lb/sf. Idk. Hopefully it's just a false alarm...
