Last Sunday my upper alternator mount setup broke a stud in the cylinder head and though we tried getting it out by drilling and using easy outs...there was no success.
I did some searching on youtube for a solution and found this video - http://www.youtube.com/watch?v=SKlYKG2vyaA . Basically the guy goes through the steps of welding a nut to the broken stud/ bolt. I decided to try it and 5 minutes later the broken stud was out...too easy! Thanks guy with Hero voice!
Nut sitting on sliver of threads - I saw another video that suggested superglue to hold in place if needed
