So today my day at work started as any would (except discovering the trash truck put a sizeable dent in the nose of the vanagon......which will be repaired free of charge), and the mecahnics at my work started working on my vanagon. I popped in from time to time to check the progress. The goal was to replace the manifold gasket at cylinder 1, so the manifold had to come off as the studs were damaged. Of the 4 bolts that connected to the heads and 2 that connected to the collection pipe (1.9L) The collection pipe bolts came right off, and 3 of the head nuts. One was not so lucky. It snapped and the mechanic welded a nut to the stud and started backing it out.....it was working really well....till it broke the stud halfway inside the head. So......out comes the tungsten carbide drill bits.......a very accurate and perfectly executed drilling went horribly wrong when the bit broke off flush with the head. "You cant drill out a drill bit" boss mechanic said.....so over the course of the weekend the entire staff is trying to figure out how to fix this without removing the head (or even if the head comes off.....what do you do?) Sudgestions so far include "Burn it out" though i dont know how, "Stronger Drill Bits" which are on order but have low expectations, and "replace the head". Any ideas are greatly appreciated!!!!!! -Craig '85GL (which isnt having its best day)
