Angry Getting Headless Bolt out of Heads

basic story, changing valve covers, while putting new covers on, one of the bolts snapped off about half way through, so im left with the head of a bolt and the other half of the bolt stuck in my heads. i weary of drilling it out so i figured i'd ask for some help befor i break out good ol' dewalt.

basically asking if anyone has a better idea to getting a headless bolt out besides drilling the center nd all that cool jazz. PLEASE any help would be appriciated, im not having a swell week so far ... Thanks Guys nd Gals

If you broke the bolt by tightening it, a left handed drill bit may pull it out. Otherwise you may find yourself using an easy out. Either way,just try not to ruin the original threaads. Good luck.

I freaking hate EZ outs... they never work for me.

One trick I learned was to get a center punch and hammer. INstead of using the punch to put a centering hole for a drill, lay it and an angle out near the edge of the bolt. Peck it in to get a bite then try to walk the bolt around by hitting the puch with the hammer (in the counter clockwise direction ofcourse). Do you understand what I am saying here? Basically unsrewing it.

And if the bolt is seized in there due to corrosion or whatever, soak it down real good, with some PB Blaster spray - that stuff is the shizzy...
And always use antiseize compound.

i think thats the best idea i have heard so far, i understand exactly what you mean with the center punch, and at this point, i have ALL the patience in the world, ill sit there for hours tapin this thing around to get it to unscrew.

i had a buddy helping me rebuild my motor, and we were going to fire it up last night because he was going on vacation today. and we were all done when we where putting the last few bolts in, this happens. ill post a video of this thing firing up once i actually finish it.

thanks for the help, i did buy an easy out kit though just in case. i REALLY dont want to take the heads off agian
