I was going over the exhast system just a few minutes ago, because ever since I put the exhaust manifold back on, there has been a rattle somewhere. I tried to loosen the bolt on the manifold, to adjust the bracket and re-tighten it. The bottom one came off just fine, but the bolt on the top one broke off. The bolt is pressed into the manifold, i'm not sure what to do about it now. I'd really like to avoid removing the manifold, as it's a HUGE PITA. Some sort of puller, maybe? Any ideas?

 

Nevermind. C-clamp, socket and hammer = success.
