Removing rusty/broken manifold studs
Removing rusty/broken manifold studs Im in the middle of a motor swap and didnt have a choice but to break the bolts holding the passenger manifold to the cat when removing the motor. So I have got to the point of reinstalling and have sprayed the all three with kroil and let sit and nothing, Ive also applied heat and still nothing. These things are stuck and I really need these damn things out so I can get this **** box back together. Headers are not an option as funds are not there, so if you have any ideas im all ears.

I broke one of mine off trying to get the cats off.
I drilled it out just a tad bigger than the stud and used a bolt with a nut on the top side.
I think you can get your hands and tools to the nut if you put it on the manifold side.

You try that double nut method? I think you thread two nuts on the stud and turn the inside nut counterclockwise (to loosen it off the stud) until it runs into the other nut. Then you just keep cranking on it until it actually grabs the stud and unthreads itself from the exhaust (or whatever part its threaded into). I did something like that a few years ago and worked awesome to pull a couple studs out of I think a throttle body.
If that doesnt work, torch the **** out the exhaust, spray pb and guerrilla grip a vice grips to the stud and try turning it that way.
If those methods fail, cut/drill/torch it off.
