Noticed today that I had a broken bolt in my crankcase under the # 2 cylinder that holds the bottom half to the top half just above the muffler, was able to make a alignment tool to drill it through but after about two hours with a easy out the easy out broke, anybody know of anything that can drill a easy out its dam hard.

You do need a miracle!! If you come up with something to drill or remove the easy out, patent it and make millions. Probably make quite a few dollas here.

Dammit that don't sound to good Myboy! Normally the bolt end will screw right out once the head is gone. I take it, it was a really small easy out?

maybe a diamond tip rotory bit and a grabit extractor. Good luck

going to call rex supply and see if there is a diamond bit or something cause a carbide bit just burns up used up everyone I had.

why dont u post a pic up, might be another alternative that ur just not thinking of. hard to say without seeing it. if u can get to it, tack a welding rod to it and pull it out. ur not gonna be able to drill through it with no bit. might have to just do whatever it takes and put a helicoil in it after.

Some times a punch and a good hard rap with a hammer will break up the easy out. Take the head off if you can, you may be able to unscrew bolt and easy out has a package.. Use this has a last effort and use good eye protection.

Its in the blind hole under the number two cylinder don't think it goes through it sheared right at the upper block so there is about a 1 inch dead spot in the lower block/cover will try to tap with hard punch maybe break it up but never been successful with that before but trying, also didn't notice any cracks in the crankcase.

i have used masonary bits to drill out head & exhaust studs before. of course dat was in cast iron block & heads! an aluminum block with a steel bolt & a high carbon easy out jammed in it sounds like de makings of a disaster! for future referrence use left hand bits to get de bolts out. i stay away from "easy outs" dey become brittle after prolonged use and can really cause some headaches
