HG Help (broken bolt)

[94TURBO5 O]

I was re-using my ARP head bolts and the lower one on #1 snapped off with 70lbs of torque. and 1/2 of it's still threaded into the block!

1.) I have new bolts now and I'm going to replace them all but would I need to buy another set of hg's since these have already been compressed on?

2.) If the broken end falls into the motor am I screwed?

1) If your tq it back down 5 more lbs of tq you should be fine (according to a summit rep I spoke to once about this problem).
2) Let's not find out...

Alright I was lucky and the bolt came out. Now what to do on replacing the hg?

I 've done similar things with crush gaskets, on airplane engines. Granted, I wasn't in the best of locations, but, I flew on the plane also and didn't feel bad about what I had done. I'm not an engineer, just a technician, but it makes perfect sense to me, and it worked, too.
Good luck

I took my heads back off after tourqing them down. I had not started the engine though. You will be fine as long as it wasn't started.

What hg's are they...and why are you still using bolts...you need studs.

I'm all done and I just went to get a new one. The other 2 I took off were obliterated and showing clear signs of 18psi.
