I have never had one I could not get out with the 2 methods I used in the vids. I replace these all the time.

That's nice, Dave, but we are talking rusty manifolds with broken studs. I bet you can still read the cast part numbers on the ones you fix!

Some of the ones I work on are so thin in the ears from rust I just weld the stainless steel stud to the manifold, since the ear broke off.eye popping smiley

Darrin, come by and try the plasma cutter on one. I'll stick to drilling.winking smiley

drill a drill bit? That's if you break a bit drilling through the stud? And you heat up the broken part?

You heat up the broken drill bit to cherry red and let cool slowly. Also works for taps. Well, work might be a strong word, it is your only hope short of cutting the hard tool out with a torch. That and taking a punch to the hard tool and trying to break it up inside the hole.

I thought I saw an earlier poster say they had a broken drill bit stuck in a manifold.

I torched the stud out last night then was able to drill the hole out and re tap it.
