need help with snapped bolt
Guys
Its funny that you should mention that C-clamp fix. Been there and done that. However, they are still a pain in the behind to anchor to the head.
Most of the time, and finances permitting, if I have a really bad exhaust leak where I cant fix it because of broken bolts, I just pull the heads and do an exchange. I know its a little expensive but when all is said and done, its a permanent fix
regards

If you are going to do the C-clamp thing, if there is a little recess where the bolt does not go all the way through, you can break the swivel foot off on the clamp and grind it into the bolt end when you tighten the clamp.

Instead of borrowing a cutting torch, I wonder if one of those little butane torches might do the trick. I saw one in a catalog - says it gets to 2500 degrees. Think it would work?
Thanks!

A butane torch will get a 6-32 screw held by needle nose pliers red hot. Anything bigger will just get warm, will not work. I was talking to a heavy engine mechanic today. He used to drill the bolt for an eazy-out but would heat it up with a torch before using the eazy-out. Said he had good luck doing this.

Now don't get me wrong but I had a different idea. Spend an hour and pull the engine. Open a beer and take your time pulling out the bolts. Replace the gaskets and throw the engine back in. Open another beer......

This has happened to most of us, but I have a pretty nifty little trick that works for me every time. In fact, the same thing happened to me and this saved my bacon. All I do with bolts that are snapped/recessed, is break out my trusty dremel (mine has the flexible extension so it reaches just about everywhere) and carefully grind a slot into the face of the snapped off bolt. I typically grind the slot to fit the biggest screwdriver I have that will fit in the hole. I typically use one of the bits that stick straight out with a tiny cuttying ball on the end. Some pb blaster and I back the bolt right out. Whole job takes about ten minutes. Sorry I didn't see your post sooner, as I bet you've taken care of it by now. But I thought I would throw this out anyways just in case, and for everybody else who has a snapped bolt in the future.
