This is the correct answer. Get the set on the right - They're called 'easy-outs', but there ain't nothin' easy about it!
I have had good results drilling a 'pilot hole' with a smaller drill, then using a drill approximately 1/2 to 5/8 the size of the broken stud.
Use lots of lubrication. Then insert the 'easy out' and back out the stud. It's a bit of work so don't get discouraged.
DO NOT USE HEAT. Heat is used to cause a thermal differential between 2 parts - your stud is too far inside.
GOOD LUCK!
All the best...

well sean i guess you had a bad experience using easy outs.Yes they can break and then its tough to get out.but easy outs are the best way to go.If your not experienced using this you should use caution.I have done many broken bolts/studs and stripped out holes lol. You tube has videos to show how its done.
No, don't use those.

Apparently you don't understand the problem...
There's a broken stud - below the surface of the block. The timing chain cover is stuck on the block. What size is the stud? 1/4"? 1/8"? Do you know?
Of course one needs to first lube all the other bolts with a good liquid thread remover (WD-40 is one), remove the other bolts and then the cover and dress the surface. That process should be understood by even the most inexperienced backyard mechanic.
It really doesn't matter the size of the broken stud, the process is to get the stud OUT.
You first try the 'easy outs', and if that doesn't work, you drill out the broken 1/4" stud, redril the hole to the size needed for cutting new threads for a larger bolt.
The broken stud is out, the other holes in the block are dressed and cleaned up, a larger bolt is used in the 'new' hole and the timing cover is replaced.
Ya need me to draw you a picture?

the question here is getting the bolt out.jack seems to understand the problem.as for the cover not coming off because of the broken bolt thats 1/2 in. below the surface i dont think thats why the cover will not come off.

For a mechanic you sure don't have much clue what has happened. The stud has corroded to the cover, the length of the cover. You want him to snap off an easy out trying to remove a stud that is siezed to the cover at least a whole inch. Then he can't even drill it anymore because there's a hardened piece of steel in there. Should I draw YOU a picture? You really can't teach an old dog anything I guess.
