> What is the best way to get a broken bolt out of the block. Two of my > water pipe under the manifold bolts broke off flush and nothing to grab. Well at least you don't have to pull the engine out to get to it. The basic technique is to drill out what is left of the broken bolt while not drilling into the block either through the side or the bottom. Start with a small size drill bit and keep it centered as best as you can. It doesn't hurt to hold the drill at an angle to keep it from drifting it off center. Before you start drilling, you might try putting a dent in the bolt using a punch & hammer. Once you have a pilot hole, the next step is to keep drilling the hole big enough to fit an Easy-Out. I affectionately refer to them as "hard-outs" because they are seldom easy. There are two styles -- tapered with reverse thread or straight with longitudinal ribs. I don't have a preference because they all suck. Try to use the biggest hard-out that will fit because if it breaks then you really have a mess on your hands. The first thing to do is start soaking it all in PB Blaster or Liquid Wrench. WD-40 works well to keep the drill bits cool. You know to squirt some more on it when you see it smoke. WD-40 is great for drilling but not so good for disolving rust. For that I prefer PB Blaster. If you fuck up the threads, you can always fix it with a threaded insert. When you put it all back together, use anti-seize grease so it doesn't snap off again the next time. Walt Yahoo!
