nunan Posted January 7, 2009 Share Posted January 7, 2009 hey, i was wondering if anyones got any secrets or tips on how to get a snapped ez out out of a bolt thats broken off below the surface. its a 7.3 exhaust manifold bolt thats rotted solid in there. head was cherry red around bolt, and i used a 1/4" ratchet to get the extractor out. extractor is only 1/4" to a 1/2" at most deep in the bolt. thanks in advance Quote Link to comment Share on other sites More sharing options...
Bruce Amacker Posted January 7, 2009 Share Posted January 7, 2009 You're screwed. I've seen (and done) bolt removal with a torch, but it's not for the weak of heart. If you glow the center and hit the O2 for JUST the right amount of time, the hole will be clean enough to screw a bolt into. No lie, I've seen it done, but my spine is only steel and not Kryptonite, so I've only done it once or twice on a customer vehicle. I'd suggest some trial runs on scrap parts before venturing in this direction. Good Luck! /forums/images/%%GRAEMLIN_URL%%/grin.gif Quote Link to comment Share on other sites More sharing options...

nunan Posted January 8, 2009 Author Share Posted January 8, 2009 thanks guys. i'm down to that option..i was heating and cooling the bolt and was able to actually get it to shatter and was drilling it out..when the bit snapped inside the head. you cant make this stuff up. so now i'm trying to burn it out. whats even better is even with the torch on the hottest flame i can get, dead center one the bolt...is heating up the head faster than the bolt.. i'm gunna keep chuggin at it but i made sure to get approval for a new head just in case i screw up. thanks for ur suggestions Quote Link to comment Share on other sites More sharing options...
BrunoWilimek Posted January 8, 2009 Share Posted January 8, 2009 I broke an exhaust stud off one time in a V10 and broke my easy out off in it as well. I was able to use a tiny carbide burr(1/8" shaft)in my die grinder and although it destroyed the burr in the process, I got the easy-out out. Good luck. /forums/images/%%GRAEMLIN_URL%%/2cents.gif Quote Link to comment Share on other sites More sharing options...
nunan Posted January 9, 2009 Author Share Posted January 9, 2009 Yeah, i ended up pulling the head and we're replacing it. i tried burning it out but it ended burning the head because the bolt was too deep in the head. the weird angle i had to use the torch at didnt help either. so i took my time today pulling the head off, got a new remanned head and tommorrow i'll slap it on. on a side note, the head bolts next to the exhaust manifold..almost as much of a bitch as the exhaust manifold bolts were Quote Link to comment Share on other sites More sharing options...
