broken exhaust stud update, where do I buy a stepped exhaust stud ? Options

[brant]

I'm trying to change out a snapped off 4cylinder exhaust stud
its snapped off pretty short... between the head and the push rod tubes... nothing sticking out.

I can only get one nut on, not two

I've tried heat, pliers, etc...
I have a set of metric stud extractors.. but they are too big of diameter to fit on the stud. (the stud is pretty close to the side of the head)

I'm going to try and borrow a welder tonight and weld a nut on
does anyone know of any other trick or tool that would work in such a tight location?

Weld the nut on and be prepared to stick a socket on it as fast as you can before it cools down...
If you cant get it after that short amount of heat from the mig gun, use a tig or torch to get it cherry hot...

Go in and out, try both directions gently...it will eventually give up.

If not, borrow an exhaust stub pipe, bolt it down to the other stud and rung a drill through the side that is broken to start drilling it out.
If you use bushings around the bit to keep it centered...and youa re very carefull, you can get the job done.

Remember the hole has a bottom to it and you dont want to go to far or you will blow a hole in the head...

I have done more than a few on my back with a hand drill...just take your time, use a jig if you can...even a piece of aluminum or steel with the right size hole it it will work to help you keep it straight.
