Default Need Help!!! Header bolt broke

Well I was tightening them down and snap!! The passenger side next to the one by the firewall bolt broke off. Would an easyout get it out? Or am I going to have to pull the head?

The craftsmen bit is a life saver. I'm sure it will work for you if you can get some leverage on the screw.

I really appreciate finding the thread for me. I don't know if the Craftsman kit will work cause my bolt didn't break off at the head, it broke like half the bolt off. I think it is flush with the heads. Im going to try to fix it tomorrow. I'm gonna try drilling in a little and using the easy out. I REALLY don't want to pull the heads. I'm so burnt out on this header install already. I feel like blowing my truck up

If there is any part of the bolt still out of the head, you might be able to back it out with some vice grips -- I had to do that on an intake manifold bolt once...

Remove the inner fender panel.If it is broke off flush you might first try taking a very small punch of chisel and a small hammer and try getting it to unscrew (back out) by tapping on the edge of the broken bolt.

dont chisel anything!!!!

I just went through that ordeal on the rocker arm bolts. take the exhaust manifold off, if there is a small bit of the bolt sticking out try and get some vice grips on it and back it out. If its flush get some left handed drill bits and back it out that way, those worked like a charm for me you have to use a center punch first though. If that doesnt work get a bolt extracture bit and drill the center of the bolt out then tap the extractor in and unscrew the bolt out this should be a last resort and its dangerous because you can drill into the side of the head. If those three things dont work take the head off and go to a machinist.

do not chisel anything you can **** up threads and the head ask a machinist if you need more advise. I bought a small tap just as insurance to run it through and make shore the threads were all right.
good luck

If you know what your doing you can take a very small chisel or punch or screw driver and with the manifold off you can catch the edge of the broken bolt and lightly tap it and rotate it backwords,being careful and not attacking it like an animal you wont hurt anything.The left hand drill bit is a good idea if its really stuck in there.
