Re: POLL: favorite method for removing busted exhaust manifold bolt

The outer bolts seem to break off on engines when they get to around 100k, it's not an uncommon problem at all. I usually weld a nut on them. Even if it's a little below the surface, you can weld them since the weld won't stick to the aluminum. Just make sure they cool before trying to back them out after welding.
