When bolting my b16a2 head onto my b20b block, I stupidly forgot to get vtec head studs, so needless to say the first bolt to get tightened broke. Feel free to mock. Anyways, I thought Id share how I went about extracting the broken stud.
I was going to use a transfer punch to start my hole, but the break in the bolt was very jagged, so i used a 1/2" drill bit to mill down to a nicer surface on the bolt, at which point I switched to a 15/64ths, made my hole for the screw extractor, tapped it in with a small maul, and turned it out with an adjustable wrench. I had soaked the hole with penetrating oil several times and let it sit for days, so when i finally got to turning it out, it came fairly easy.
Any questions, ask em. Oh one more thing, its very important to be paitent and calm when attempting this job, its a pain in the ass no matter what. but going at it like a moron without the proper tools will just frusterate you and break more stuff.
tips:
-The square type of screw extractors/easyouts DO grip better than the spiral.
-When you use a drill press jig you CAN drill full bore in one shot. No pilot holes. The reason people bitch about breaking three or four drill bits trying to do this type of thing, is they do it by hand and get the drill on a bad angle, snapping the bit.
-Patience, paitence, paitence. If you get pissed off, stop, go drink some beer and go back at it tomorrow.
