Broken Exhaust Bolts - machinist or exhaust shop?
i'm in broken bolt hell right now.
i have a Pontiac 389 that has a lot of miles on it, and on of the exhaust manifolds actually cracked in half. i have the motor out right now to fix a couple other items on it. wouldn't you know, that on that side of the motor, there were 4 bolts that broke - even with heat applied, and PB blaster soakage. other side was fine, makes me wonder why one side (drivers) would have so much more problems.
anyhow, i've given up on trying to extract them myself. in fact, i wonder if i even buggered up on of the holes while trying.
so, i'm going to just take the head off and take it to a pro. but i'm wondering if i should take it to a machinist or exhaust shop?
