Broken Head Bolt

[olzed]

So, after all the investment and input here, can you elaborate on how the shop got the bolt out?

Please, so we all learn something.

$100 sez the mechanics didn't do anything that wasn't suggested here.

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.

Wade is right the mechanic didn't do anything.

The block is back home situation unchanged i need to find another mechanic or shop.

No big deal i might try to do it myself you never know what you can do or how well you can do it until you try

The glass half full...

Do you mean he did not extract the bolt? can you post a picture?

[slowride]

That's what I'm saying he did not extract the bolt.

I gave him two days and he kept saying he was soaking it and im not paying anybody to just look and spray oil on it.

I cant post pictures im still learning this whole internet thing but i will let you guys know my next step

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.

That's what i was thinking i just need to do some searching around for a good shop i my area

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.

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.

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.
