RE: [DML] exhaust manifold problem - what would you do?

Sometimes the best tool to use is time - time soaking in PB Blaster, Kroil, 
or some other penetrant, that is. Be sure to allow any penetrants you are 
using a lot of time to work. Days, if necessary. (Of course you have to keep 
reapplying penetrant periodically as it wil evaporate.)

Sometimes even penetrant and a lot of time does not work, however. You can 
also try heating the remnant of the stud to red hot and letting it cool 
before removing, and could try spot welding a good 11 MM nut to the stud, or 
double-nutting it so that you can try the wrench again before resorting to 
stud extractors.

I think the Dremel idea is a good one since it will leave you with a 
protruding stud that you can then work on. I would not try turning that one 
out in its present state since you may break the stud off flush with the 
ehad which would complicate things. By cutting off the bolt head you'll be 
left with somethng to work with.

Good luck!
