June 28, 201212 yr comment_394271 For $40.00, I would guess they put in a heli coil. I agree with the rest....we try to give advise, then don't learn the solution. Very frustrating.

June 30, 201212 yr comment_394444 Don't pay for no result.I second that! Stuck and broken bolt are a pain in the butt. Still do not give up hope. they are a pain but not impossible to remove. Just do not cause more harm than good. I would stay away from "easy outs". If you you break one it become a "difficult out". I have never had a fastener I could not get out eventually. But if you are really that stuck take it to a machine shop instead of a mechanic. A good machinist will have it out in less time and will probably cost less.

June 30, 201212 yr comment_394459 Have you actually tried everything suggested here? Heat it with a torch for 20+ minutes, until the surrounding block is nice and toasty. Get the bolt cherry red if possible. Immediately apply dry ice to the bolt head, have several pounds of it ready. Then vice grips, or a pipe wrench if you can get one on it. After that, find a machinist to weld a nut to it...and do it again! I concur, I'd stay away from the EZ outs. If it's in that tight it's just going to break off the EZ out.

June 30, 201212 yr comment_394461 Ok, here's my last input on it- I swear. The last sheared bolt I took out I ground the top smooth, used a punch, and made a divot as close to the center as I could (this step is VERY important). I then took a 1/16" bit and drilled. I went in small increments with progressively larger bits until I got near the meat of the nut I was trying to clean out. I then ran a tap into the nut (block in your case). The tap took out the remaining shards of the bolt and I was able to get a new bolt in. If you do not center the punch/first drill bit properly, you run the risk of drilling into the block which you do not want to do.When you run a tap, you need to use a lubricant and keep going forward and backward to allow the removed material to drop out and not bind.

June 30, 201212 yr comment_394473 Find a friend or a friend of a friend with a MIG welder and weld on a nut. I would be shocked if he charged you more than $20.Chuck Link to comment https://www.classiczcars.com/forums/topic/43596-broken-head-bolt/?&page=3#findComment-394473 Share on other sites More sharing options...
