There is not much you can do unless you have a high speed die grinder with a small bit to grind out that easyout. You may be best off to go to a repair shop to have them do it because even if you get it out you probably need heat to get the bolt out.
I have a high speed die grinder, air supply and a torch. Please tell me more about the bit to use and the technique. Thanks.
If I heat the bolt, won't I be heating the cast iron block too and then cooling it quickly possibly crack it or are my concerns unfounded?
Ok, keep your fingers crossed for me, and I'll let you know how it turns out.
I saw a suggestion in a forum about welding a nut to the broken bolt. The bolt and extractor are broken below the surface. How would I weld to the bolt in that situation, and what do you think of the idea in general?
Any suggestion on preventing the nut from becoming welded to the top surface or internal threads while welding it to the bolt?
