Broken exhaust stud removal...

[Ameer Antar]

Also, instead of liquid wrench or wd-40, I've used something called
PB-Blaster which is orange when it comes out. It works much better at
corroded parts, esp. on exhaust stuff. Also don't forget about adding a
little heat around there. Adding heat to a hole makes it expand and it's so
much easier to remove parts after a little heat in the right place. Make
sure not to use much b/c the head is aluminum, just a few seconds of a low
flame here and there. And make sure you heat only the head and not the
stud, otherwise it will expand, and it'll be just as tough to turn. But
since it's aluminum, the head will heat up much faster than the stud. I
think all of these tips combined should do it. good luck.
