Still Stuck

Ran the heat treatment with Map gas several times.

Dilled 1/8" pilot hole, BP Blasted and then followed with small easy out and Snap-on screw extractor. Nothing.

Drilled 3/16" hole and followed same procedure. Nothing.

Drilled 1/4" hole and followed same procedure. Nothing.

The hole appears to be slightly off center now and I'm concerned about the threads. I ran a 5/16" drill bit in about 3/16" of an inch. Threads are ok, but I still can't turn bolt with any of the tools.

I decided to quit for a while and think things through. I guess the only option is to either drill on with the 5/16" bit and hope the threads are ok and that the bolt colapses. I don't think it will work as the bolt is frozen in and that's why it broke. It wasn't like external weight or pressure caused it to snap.

So assuming I'm correct I guess there is a procedure for drilling out and inserting a timcert. Can I do that? Also, the portion of the block where this is is not too meaty, so the replacement bolt would most likely be smaller, maybe 8M.
