removing broken arp stud?

[bassman31386]

anybody have any clues of how to remove a snapped arp head that has about 2" or so exposed from the block? the bolt should be torqued down to + 70 ft-lb since, for some reason, the nut decided to seize on the stud without telling me. right now, i have only thought of the following solutions:

1. grind a slot in the top and use something like an impact driver/anything else that can get me some leverage (might actually work)

2. use an easy out , but i doubt it would actually grab the hardened steel that the stud is made out of, and i really don't think it would hold for the amount of torque that i need.

3. drill the bolt out, tap, helicoil, and replace with new stud

4. grind two of the sides flat so i can get a wrench on it

5. go to town on it with a set of vice grips set so tight that you have to use a second set just to close the first, and wack it with a hammer. I still don't know if the vice grips will grasp the stud since it is pretty smooth.

6. (probably the easiest) have someone weld a bolt to the stud and remove it just like any other bolt.

that's all the ideas i have. i need this stud out this weekend since it is the only thing now that is keeping my motor from running. it's things like this that really mess up a simple head gasket replacement.

I think welding a bolt is about your only hope, does ARP replace it?

you still have some sticking out? try with the vise grips, as you don't really want heli-coils in there holding the head.

yeah thats the kind of luck that some get, a camshaft cap bolt snapped in the bolt hole, not lettin me finish doin a headgasket job in my car.(tried easyouts, that didn't work so i had to drill & use heli-coil)

A helicoil will be just as strong as cast iron, and stronger than aluminum. My $.02.

I agree with the welding comment

i have no idea if they would replace it. i mean it torqued down fine with the first headgasket so i don't think it's really their fault. the nut is still stuck pretty tight on the broken piece of stud that i have and it won't budge. so it was either just a freak accident or some foreign object got caught up in the threads that i didn't see. either way i was able to get a single replacement stud, nut, and washer for $15.

yes there should be plenty sticking out considering the stud broke off right below where the washer sits for the headstud. i didn't actually bother taking the head off again since it pissed me off so bad, so i just went to do some other things i had planned for the day (removed clutch dampner box/install new slave cylinder, install exhaust, install caliper, etc). i figured that i would just worry about it this coming weekend after i had time to think the situation through.

If there are threads on there double nut it, if that doesn't work, weld a nut on.

Take a look at this: Go to Sears, Snap-on, Mac, any well known tool vendor. They have a tool call a stud remover/installer. It works on the eccentric principle. I bought mine around 20 plus years ago and its still going strong. Mine happens to be a Craftsman and their cost is around 25.00 dollars. (Craftsmans) Go to http://www.pcmidgets.com and check out my race car, it is the # 66 midget. It is getting a 2.4 ka24e installed as we talk. Have a good one.

hmm. . . i didn't even know they made those. i'm definitely looking into that. thanks

Yep, stud removal tool is how the pros do it

Its basically a one way bearing, the rollers are eccentric and some have a flat edge, works great.

This week eh Mike? Cant wait to see that beast in action

If you really have 2 inches sticking out, slap a pipe wrench on that sucker. If you don't have a pipe wrench, then you could buy the tools mentioned in the above posts.

Yep a pipe wrench would work

But a word of caution, depending what size you have ( as in length of handle) the leverage you impart upon the stud could break it off at the deck surface or below - I know been there done that many moons ago.Just don't get into a hurry on it and think it out.
