If there is any of the stud sticking out, I use a oxyacetalene torch to weld a nut on the remainder of the stud. The heat from the torch helps to release the stud from the head.
For one that is broken off inside, I make a drill guide jig and use a left hand drill bit that is slightly smaller than the broken stud. For a 914 exhaust stud, I use the cast end off an early heat exchanger as a drill guide. Patience is the key. |
