I had one last broken bolt, well I hope it is the last, to drill out on the intake housing. I really suck at doing this. I never seemed to be able to get the punch centered and therefore my hole is not centered and often isn't drilled straight. I really hoped the piece would come out while I was drilling it but no such luck. I tried feeding in a tap from the back side but it just kept kicking off at an angle and binding up. So I kept going bigger with the drill bits until all of the old bolt was gone. Unfortunately this meant I drilled into new aluminum on one side of the hole (because my hole wasn't centered). One saving grace is that the broken bolt didn't got all the way through the tapped hole. So I decided to try the JB weld trick I had seen online. Spray a new bolt with WD40 or something similar. Put JB weld in the hole, thread the bolt in. If it works right I should be able to break the bolt free, thread it out, and be left with a nice threaded hole. If it doesn?t work...well I get to drill out the same hole again.
