Broke off two head studs pulling the old heat boxes to put on my header. (IMG:style_emoticons/default/headbang.gif)
Do i drill them out and try to get something to fit or just start on my GA rebuild? Was planning on driving the car while i did it, but... BTW this motor will be scraped since it's a bus 2.0 once the real engine is done. |

I assume you're talking about exhaust studs. Is there anything left of them sticking out? Welding a nut onto the end can help, also careful application of heat to the aluminum boss can help the broken stud come out.
Drilling is very risky. I've done it a few times successfully, but it's not easy and it takes a lot of skill in being able to estimate angles and depth. If you go too deep you'll break into your exhaust port. If you go in at the wrong angle, your exhaust won't go on. A slight misalignment at the head, becomes a large misalignment at the end of the new stud. Good luck. (IMG:style_emoticons/default/sad.gif) |

(IMG:style_emoticons/default/sad.gif) Thanks. Tried the weld nut on stud thing, just twisted the stud off again. I was just thinking about it, think i will make a drill guide that i can bolt to the opposite stud with the proper size hole and angle to help guide the drill. If that don't work guess its on to plan d,e, or f-it. |
