Loose Head Bolt

One trick with hard outs, is do not drill all the way through the broken stud. That way the easy out will hit the bottom of the stud. It will not put as much pressure on the sides of the stud, which makes it expand the stud in the block even more than it is.
 
Put acetone an Automatic oil 50-50 on the stud .leave for 3 or 4 days it should be loose by then .I have welded low profile nuts on studs on big engines with great success .The welding will loosen the threads .If the stud is broke at the gasket level the head has to come off. Good luck
 
If anyone every meets a former senior experienced military demolition instructor, one can recognize by his instructions that teaching "what not to do" appears so natural.

Teaching and learning "what not to do" with Trip Wires, Shape Charges, C-4, Det-Chord, Claymore Mines, Anti-Tank Mines, TNT, Dynamite, Blasting Caps, etc., is far more important than teaching and learning "what to do" with these items.

The only good easy outs I've ever seen or used is the ones we had in the Army. They had a straight shank with sharp barbs running the length, so as you tapped them down into the hole you drilled in the broken stud, they grabbed on without expanding the broken part. I've never seen them since I got out of the Army, but wouldn't mind finding a good set of them.

I have a set of that type made by Snap-on tools under the Blue Point label. There are some listed on ebay. This is a set that for sure is staying in my tool box. :)
 
Easy-outs can work, but they are not magic. If you don't do anything to get the threads loosened up first, how do you expect the smaller diameter extractor to not break, when the larger diameter bolt already broke? It can take days and days of penetrating oil, heat, cold, impact, and praying! to get a stuck bolt or stud to come loose. Take your time, use a short tool on the easy-out, if it won't come out with fairly lite force, it's not ready!
