White93z34 Posted August 17, 2006 Report Posted August 17, 2006 alright on a L36 that we're puting headgaskets on, was torqueing the rear head down to 90ft lbs, and it snaped. i'm thinking a few good sharp drill bits, and a easy out? and yes, these are brand new headbolts. Quote
19Cutlass94 Posted August 17, 2006 Report Posted August 17, 2006 The only way I know of is some drill bits and re-tap it if needed. An easy out may do the trick, but theres gotta be something there for it. Quote
Crazy K Posted August 17, 2006 Report Posted August 17, 2006 in a magazine I read, they welded a nut to the broken off bolt... basically, they introduced a piece of copper pipe (as a sleeve) for the remaining length of the bore, and a stainless steel washer to sit at the opening of the bolt hole, and placed a regular nut on top of the washer.... and then welded through the nut, into the opening of the hole. They welded until it had welded the broken off bolt to the nut, a spand of a moderate distance.... The copper pipe and stainless washer prevent welding to the block. Quote
19Cutlass94 Posted August 17, 2006 Report Posted August 17, 2006 If I understand that right, hes saying weld a nut onto the remaining part of the bolt and then try to take it out that way. ( short version ) Quote
Crazy K Posted August 17, 2006 Report Posted August 17, 2006 If I understand that right, hes saying weld a nut onto the remaining part of the bolt and then try to take it out that way. ( short version ) yeah, by bridging the gap between with the welded in material. anyhow, it seems like a big gap to me Quote
runt Posted August 17, 2006 Report Posted August 17, 2006 I would drill, tap and try to remove that way.... Quote
R Dubya Posted August 17, 2006 Report Posted August 17, 2006 well if the easy out breaks, then you are in a world of shit because those things are hard as hell and difficult to drill into. Is there any bolt showing outside the hole when the head is off? Can you even remove the head? If you can get a nut on it and have it welded than thats the best bet as long as it doesn't end up welded to the block. Quote
5speedz34 Posted August 17, 2006 Report Posted August 17, 2006 I would try an Easy Out. But I know Pabz had the same problem earlier this year. Look up his post. Quote
White93z34 Posted August 18, 2006 Author Report Posted August 18, 2006 well its out. the bolt was broken off just under the deck, so we had the head off anyhow. got a 1/8th inch drill bit, drilled far down into it, pounded an easy out into it, and after a few turns it grabed and pulled the remainder of the bolt right out!

They welded until it had welded the broken off bolt to the nut, a spand of a moderate distance.... The copper pipe and stainless washer prevent welding to the block. they make welding rods for that with a special coating that coats the hole/threads that you're welding down into so the weld does not stick to it.

Mach 5 Posted August 18, 2006 Report Posted August 18, 2006 If there is a little bit of the bolt sticking out, you can cut a slit in it using a Dremel and using a flat head screwdriver to take it out. Or you can drill and tap the hole. Quote
