boonedock saints Posted March 11, 2014 Report Share Posted March 11, 2014 Ok so one of the twins ended up tightening the shit out of one of the oil pick up bolts and snaped it off, then the extractor broke off in the bolt when trying to get the broke bolt out. I have not been able to penatrate the hardened steel of the extractor, it laughs at my drill bits, Ive tried using a punch to start it turning out, but nothing...any ideas, or alternatives, suggestions...jokes..? 1 Quote Link to comment
mklotz70 Posted March 11, 2014 Report Share Posted March 11, 2014 You might try a masonry bit. They're carbide tipped. Just sharpen it with a grinding stone or abrasive wheel to get a sharp cutting edge. Quote Link to comment
JNHEscher Posted March 11, 2014 Report Share Posted March 11, 2014 Any time I snap off an extractor, I tig weld a hardened rod to it and turn it right out. The heat expands the metal and then it contracts enough to spin right out. Works every time, but a tig weld is needed. 1 Quote Link to comment

I was trying to avoid this, but I pretty sure it will work as well, thanks for confirming. Quote Link to comment
smoke Posted March 11, 2014 Report Share Posted March 11, 2014 I have done this a couple times myself. After weaving a tapestry of profanity over the situation, I break out the welder. In one instance, I blew it out with a plasma cutter, but I think I got lucky by not boogering it up, so maybe don't try that one. Quote Link to comment

Well, couldnt wait for my cousin to get home to use his TIG, so ...heat, punches, drill...repeat...and then casting broke off....ahhh F&*@ MY ASS...was able to recover by using a 1/4 inch bolt washers nylon nut lock tight, the one good bolt seemed like it would do fine, but didnt want to take any chances of sucking air. Soooo as embarassed and ghetto as it sounds it will be fine for what the function is. If not then I will learn something from this....Dont let your son tighten a 12mm bolt with a 3/4 drive.....my fault for assuming I guess...ahhhhh Quote Link to comment
dr.feltersnatch Posted March 14, 2014 Report Share Posted March 14, 2014 post pics of the carnage. we might be able to help you fix it and if not at least laugh at you. :rofl: no seriously though there are a lot of machinists and stuff on here and there might be a way to fix it.

WOW...way to put me on the spot, a freakin laugh it would be trust me....the whole side of the curved portion is blown out, its like a half circle with threads. Im assuming to through trying to get what I need to weld cast, Id be better off just starting with another block...which is not in the cards at this time. Im fairly confident...lol... the through bolt + the other good side will work for what the function of the oil pick up is...the elements are gong to be vibration and heat, not really any sheer stress. But if I grow a set over the weekend...Ill take a picture....and you guys can point and laugh....Im thick skinned... :blush: Quote Link to comment
72240z Posted March 14, 2014 Report Share Posted March 14, 2014 You can just tig a nut where the casting broke. Would be much better then just leaving one bolt. I would be concerned with sucking air but also the constant vibration, heat/cold etc... loosening the one bolt up over time. 1 Quote Link to comment
dr.feltersnatch Posted March 14, 2014 Report Share Posted March 14, 2014 exactly my concern. ever try to drink from a straw that has a hole in it? you dont want that happening with your oil. Quote Link to comment
boonedock saints Posted March 14, 2014 Author Report Share Posted March 14, 2014 exactly my concern. ever try to drink from a straw that has a hole in it? you dont want that happening with your oil. Oh I agree, but there ARE two bolts in the stock locations for sure....one just happens to be a through bolt with a nylon nut and lock tite on the back side, the other side is stock and not broke...YET...I wouldnt run with just one by any means. Had to use a through, or decided I should say use a through bolt on the side that blew out or cracked off, during the attempt of removing said extractor. Everyhting is very secure and should function as normal.....just a bit ghetto... Quote Link to comment
HRH Posted March 16, 2014 Report Share Posted March 16, 2014 Depending on how anal-retentive you are, you can use the right stuff as the gasket material and tighten down the one bolt. After that shit cures, it's not going anywhere. I'd want to fix it right, but if it's just a ho-hum motor or you need to get it running, it would work. 1 Quote Link to comment

JoeCool Posted March 21, 2014 Report Share Posted March 21, 2014 I was about to say... HOLY HELL! Nine freaking days later and you still haven't fixed it? Damn, talk about procrastinating! :P Then again I did drive around for three months with a squealing belt on my Datsun before I finally gave up and tightened it! :blush: Quote Link to comment
