IM NEW TO THIS. BUT ANYWAY I HAVE A 97 WOLVERINE THAT IM DOING ENGINE WORK TO. WHEN I WENT TO REPLACE THE EXHAUST ONE BOLT WAS ALREADY SNAPPED AND THE OTHER ONE BROKE WHEN I HAD LIKE TO TURNS LET ON THE NUT. ANYONE HAVE ANY IDEAS ON HOW TO GET THEM OUT OR HOW MUCH THEY ARE TO GET MACHINED OUT. OR WORSE CASE WHERE I CAN FIND A NEW CYLINDER HEAD.

 

This is what you will need to get them out..
1. Sharp punch
2. Drill
3. Very sharp drill bit
4. Easy out

Ok Take the punch and a hammer..Put the end of the punch in the center of the stud..Hit it once HARD..Making a little dent in the middle of the stud..So the drill bit will stay in the middle of the stud...So take your drill bit..And drill into the stud about 1/4 or a inch..It will take awhile the studs are hard....Then after you get your hold drilled take your easy out and a hammer and hammer your easy out into the hole...(Keep it strait) Then take whatever you got handy and screw the easy out..out and the bolt should come with it...Hope this helps

 

THEY DIDNT COME OUT WITH EASY OUTS. THE TOP STUD SNAPPED THE EASY OUT. SO I GUESS ALL I HAVE LEFT IS TO FIND A NED HEAD OR TRY TO FIND A MACHINE SHOP TO GETEM OUT.

 

Ok well its very hard to drill out a easy out..I had my local machine shop drill a easy out for me..They Charge me $50.00

 

Do you have any stud sticking out of the head? Or is it broken off flush? If you have some stud sticking out, get some "pb blaster" or even better "aerokroil" and spray on the bolt for a few days to loosen the stud, also lightly tap the stud, the vibration of the tapping will help break up any rust or seizing that might have occured over time. Then take a GOOD brand screw extractor, like "IRWIN VISE GRIP extractors" and try removing it that way. You might have to lightly hammer the screw extractor onto the stud.
If the studs are already broken off flush you have no choice but to drill them out, and good luck with that!
