    Holy Crap........what do I do now?

    As I was removing the main case bolts, one of the case bolts heads rounded off! Yes that is right. Not a tool problem. I have used the sockets many times before without problems. Any ideas?

    I guess take it to a machine shop?

    drilled the head of the bolt off.... the cases will still come apart.

    when u split the cases the rest of the bolt stud will remain and try your luck at it then.. had it happen once and was able to remove is that way

    That bolt is pretty hard...cut it with a dremmel/cuttoff wheel

    Once the head is drilled out or cut off that will release the pressure on the bolt when the cases are then pulled apart you should be able to screw the remainder of the bolt out by hand. If you can't use vice grips and just a little heat if necessary to break the loctite. (did an intake manifold bolt like this last week)

    i've seen some people weld another bolt to the rounded one if it's accessible.

    The bolt was one of the case bolts that is deeply recessed. Drilling is the only option I think. I am waiting to hear more from Steve on how he did this (drill press, hand drill, etc.). These bolts were noticable tighter than the other 4 Tec engine I tore down.

    once you turn it into a stud, use heat to free the loctite.

    it really wasn't all that hard to drill the head off. i used a hand drill... keep spraying oil on it, start with a small drill bit and try to get yourself as centered as possible on that bolt head.

    also try to use a punch and whack it to start a dimple in the center maybe...

    guess this is all gonna depend on how good your drill bits are...

    you can't get in there with a cut off wheel or dremel or anything... drilling the head of the bolt off is about your only option... don't sweat it tho, you'll get it off fine
