ok earlier today i replaced my leaky cometic with a fel-pro permatorque $30 headgasket hoping to fix the problem. everything was going fine until it was time to torque down the arp head studs. on the final torque step one of the studs (# 5 of the torque sequence) did not want to torque down to specs, but it just kept spinning until i heard a loud CRACK. it turns out that the stud broke off towards the top. i'm not sure what happened exactly, but i think the nut somehow got jammed on the stud, but it wasn't crossthreaded . anyway, do you think that i would have to get a new gasket since i torqued down some of the bolts, and i'm pretty sure these gaskets aren't meant to be reused. sorry for the long post but needless to say, this severely pissed me off. oh and does anyone know if it is possible to get just one stud/nut/washer set from arp because i really don't want to spend another ~$100 just for one stud.

no the gasket is good but your block is fucked if you cant get that broke bolt out. try cutting a slit in it with a punch and use a flat screw driver to get it out. those bolts are hardned so that might not work. try and easy out. but you will probaly have to drill it out. dont run your engine with out fixing it.

yeah i've been thinking about that all week. so far i've come up with the following solution with #1 and #6 probably being the best

1. grind a slot in the top and use something like an impact driver/anything else that can get me some leverage (might actually work)

2. use an easy out , but i doubt it would actually grab the hardened steel that the stud is made out of, and i really don't think it would hold for the amount of torque that i need.

3. drill the bolt out, tap, helicoil, and replace with new stud

4. grind two of the sides flat so i can get a wrench on it

5. go to town on it with a set of vice grips set so tight that you have to use a second set just to close the first, and wack it with a hammer. I still don't know if the vice grips will grasp the stud since it is pretty smooth.

6. (probably the easiest) have someone weld a bolt to the stud and remove it just like any other bolt.

I did that on my buddies Honda when he broke his bolt. Didnt use a hammer but the vicegrips gave me something to hook a wrench between. Worked fine. Took me about 45 minutes to get the grips off though.......

is the bolt sticking out of the head? if so your golden. just go to sears and get a set of "fucked up bolt" removers, there $10 and you will have them for a lifetime. if your to cheap cut flats on each side and use your friendly open ended wrench.
