I had a stuck head bolt on my 84 duke. I used a long piece of tube to get enough force to break it loose but i broke the bolt in half. Now i got about 1/4 inch of bolt sticking out of the block. What is the best way to get it out.

If you are lucky and persistant...

I would drop a nut over the bolt and weld the inside full. LOTS of PB Blaster and wiggle it back and forth, not just force in one direction. Good luck and use persistance more than force.

i thought of that but there is like no treads to even get the nut over.

You will have to drill out the bolt center and use an easy out. I had the same thing happen when I helped a friend build up a hot rod 500HP Z-28 recently. I drilled a small hole straight down into the head bolt part around 2" deep. Then I drilled a little larger hole, and a little larger hole until I was able to get an easy out into the center of the bolt part that was big enough that it would not break easily. I PB Blastered the heck out the the bolt part (soaking and respraying for 2 days!) Then I turned out the bolt a little, blastered it again, and finally got it out.

I tapped the threads to make sure they were OK and Voila! I was done.

Good Luck, Gary.

Thank i will try that where can i get easy out and what is PB blaster and where do u get it?

The threads do not matter, use a nut that is one size to big. If you have a 1/4" sticking up it should be enough.

If not then do what Gary said. Just be very carefull to keep it centered! Buy sharp new drill bits and GO SLOW! I would start by grinding the top of the bolt flat to be sure you can punch it exactly in the correct spot.

Blaster is common now at most parts stores. It is a penetrating oil. It is the best, settle on nothing else.

I'd do what electrathon suggests before trying an EZ out. I'm batting .000 lifetime with EZ outs and if you break the EZ out off in the hole then you are big time screwed.

Once you get a nut welded on I'd trying zapping it a bit in both directions with an impact wrench to try to break the bond.

When I changed the head gasket on my 84 last year I had two head bolts on the exhaust side break. One stuck out of the block about an inch and the other one about 3/8". I thought I was in a world of hurt, but as it turned out they both came out easy. The one that stuck out about an inch just unscrewed by hand and other one came almost as easy after I sprayed some penetrating oil on it and then clamped some vise grips on it and turned.
It seems the bolts didn't break because they were not stuck in the block, but because they were stuck in the head. There was a lot of rust and corrosion on the shaft of the head bolts on the exhaust side.
