or buy an eze-out


broken bolts have got to be the worst.......I would personally take a stripped thread hands down (usually).....

 

they dont make easy-outs long enough....I went to harbor freight already....

 

shitty..........

 

tell me about it...gonna give the reverse drill bit a try again....I am deserate now

 

have you been able to even drill a hole in the bolt?

 

nothing is working.....may just have to suck up the $300.00 and have it towed anyways

 

Yeah, I got a hole drilled into it....I just went and bought some smaller easy outs....and Nino is on his way down....the same thing happened to him, and he got his bolt out, so we'll see, keep your fingers crossed or say a prayer for me will ya????

 

Well, we have drilled into the head bolt, broke 2 drill bits and an easy out. So today, I am running out to get a longer drill bit....will let you all know what happens.......oh, and just for good measure IF ANYONE DOES A HEAD AND CAM SWAP, USE HEAD STUDS!!!!! but then again, thats just my $.02..

 

if you think about it unless the bolt was really shitty it would take a good amount of torque to break it, that adds up to pressure between the threads of the bolt and the block and in the non perfect world that we live in: friction.

What I said was that as much force that he gave to break the bolt off it will take at least that much to bring the piece back out. It was friction that grabbed the business end of the bolt in the first place that made it twist and break off.

Get a good extractor, and I feel for you. you mat have some luck heating the block to enlarge the hole. I have no idea how though, and if you get someone to weld something on it wait until the bolt cools down before you try to extract it.

 

**** it run it without one head bolt...what do you have to lose?

 

Yeah, but its the #1 bolt on the head...right in the middle.....I am towing it down to JBA tomorrow and let them try to get it out....I have a feeling that they may have to tap the treads and get me a bigger head bolt......

 

good luck man

 

thanks....I hope they call me tomorrow with some good news

This is what I did to get my bolt out of the block

 

That blows. I did not use the standard procedure for tork-to-yield bolts for my heads....

I just torked em to 40lbs, 50lbs, 60lbs 70lbs and finally 75lbs.....in a planned sequence from inner bolts to outer bolts - like in the old days,....

I have no idea what the proper final tork reading is supposed to be for gen 3s... my heads have been on 3 years with no issues, however.... so 75lbs must be close!

I did this only after spraying the new bolts with silicone and realizing that they could not be marked with a felt tip pen whichis used in the standard procedure recomended by GM.....

I thought the long lenght of the head bolts was due in part to the fact that they are clamping alumuium and not iron....

....my suggestion on the broken bolt extraction would be to get professional help. Find someone who has helped people who have had this happen and who can give you good odds of success...

Did you hear about the guy who broke his crank bolt off inside the crankshaft. He got professional help and the bolt came out.

IF all else fails, I dont think a new block is the fix since you can;t pull the innerds from your motor and throw them in a new block without machining and expenct it to work great...

This is why you need professional help!

 

I wish mine came out that easy.....we'll see what JBA can do with it tomorrow, I will keep you all posted. Thanks for the help..

Yeah, I hear you...but there is a shop in Oceanside that have used short blocks up there....he said they have about 10 of them...and hell, it will get me running at least:dunno:

 

I think you have at least a 50% 50% shot.

Don't panic - just get professional help!

 

One of my friends from a local board JUST had this happen to him. He went to a local hardware store and bought a screw extractor. I think it was Ace. With the tool, you will want to turn it with a 1/4" socket on a 2" ext. with a small ratchet. You will have to first drill to flatten the top of the bolt then drill a hole down the center of the bolt. Then use the screw extractor to get a bite on it and twist it out. It took a bit of time, but the damned thing finally came out.

So, did you try and flatten the top of the bolt before drilling the hole? If not, you may want to see if that helps.

 

Oh, I passed panic, and stress last week....I am supposed to be driving to NC tomorrow looks like I am delaying my trip
