    Is any of the bolt sticking out? Or is it broken flush with the end of the crank?

    Oh, it's not even that good. It is broken off about 3 3/4" deep into the crank.

    Well that is a big problem. You're gonna have to drill it out. Very carefully.

    I don't think I'd attempt to drill it, unless it was removed and on a bench. That's the safest way. You might get lucky with a left twist drill bit or an easy out, but it's still a dangerous thing to do.

    Well, I just talked to a local auto repair guy here. And he said that since it is that deep in there that it would be very difficult to put an easy-out on it. Because you can't get one much longer than about 3 to 4 inches long. He suggested getting the car to an Automotive machine shop to see if they could do anything with it.

    Ouch! If you try to do it yourself, use a short piece of pipe as a sleeve to both center the drill bit and protect the threads in the crank. Left hand bits and/or a long easy out are a must. Be very careful not to break the bit or easy out off!

    You know what Jeff? That's a very good idea, using a short piece of pipe to keep the bit straight. But here's the thing. It was an ARP bolt that broke. Do you think a bit would still drill into that type of material?

    get a metal drill bit and put a little bit of oil in a squirt bottle, if you have a variable speed drill set it to the drill setting, don't go full trigger, quarter to half at most, as you drill apply light to medium pressure and squirt some oil onto the cutting faces of the bit as it drills. This is best performed with two people and in your situation i wouldnt attempt it alone.

    Was the crank bolt a lil hard to tread in ?
    If it wasnt it should turn right back out use a small pick an start working it counter clockwise to turn it back out

    I am speaking from experience it has worked !

    When I did it since I had a steel crank we welded a bolt onto it CAREFULLY and backed out the bolt. Put a nut over the bolt to avoid splatter into the crank

    No. The bolt was very difficult going in. I had read a bunch of threads about installing the SLP Underdrive Pully. And almost everone said that you didn't need that tool that SLP says you need for the install. But the mechanic that I spoke of earlier in my thread said that he never puts on a balancer with out that tool. He said when using that toll, the pully goes right on.

    You have a bad situation on ur hands now .

    Is the balancer all the way pressed on?
    If it is then just drive it it won't come off

    Well, no. It isn't. It lacks about 3/8" of an inch being where it needs to be.

    How did you break a crank bolt ? I thought they were grade 8. If you have the means I would tow it to a machine shop and let they take care of the problem. Remember, if you mess up the crank then you have to drop the engine and depending on your mileage you may want to rebuild it while you are in there. It may be a good thing if you have the time and money but your car will be off the road for a month. I hope they can get it out for you. If they do please buy the best crank bolt ( ARP ) you can buy and use anti-seeze on it. Good luck.

    +1 on the ARP hardware, have you tried any home remedies yet or have you decided to pass it off to a shop?

    Time to pull the crank.....:/

    Prolly cheaper to just replace the crank than have it worked on @ this point..

    Just as a future heads up,, next time try running the bolt in by hand first.

    That's a hardened bolt no matter whom makes it, and only serves to keep the balancer on,,

    the balancer does NOT ride on the bolt.

    No need for above stock replacement (insult to injury stuff,,sorry)..

    If it does'nt go in most of the way by hand,,,, Houston we have a problem..

    Check your threads,,, and try again.. good luck.

    Hey Guys. Thanks for the interest in my problem. I'm going to try what Jeff suggested. I am going to try to drill it out. Jeff suggested using some small, short pieces of pipe that would fit in the hole on the end of the crank. Using the pipe as a guide, the drill bit will stay centered on the broken piece of bolt. And that would also keep me from damaging the threads. I'm not going to be able to try it until this weekend.

    Oh. It was an ARP bolt!!
