Did you say "easily"? hah heh hah {cough} Okay... Luckily I didn't break any off flush, but one did break flush on my intake manifold. I messed up the threads getting it out. As for exhaust manifold studs, Martin suggested making a plate with holes as a drill guide. I think this is a fantastic idea, but it would take some precise tooling to do a good job making one. > How much you want for one? One of them is already hollowed out, and I paid $50 for it. This is the one I was wanting to sell. But for the extra price you are ahead with Ed's pipe. The other one came off of Adam's car and is all intact, but I would rather keep that as a spare. > 1. Heat the area around the stud and cool That didn't do much for me. I could heat the stud until it was red and then a second later touch my finger to the block next to it and it was COLD! Next time I will plan on running the engine to get the whole block hot. Then freeze the stud. > 2. Stud extractor I used the big clunky cam style extractor. There wasn't enough room to use this effectively on the upper studs. I suggest getting the smaller style one that looks like a socket with a pencil sharpener hole in the business end. > 3. Double nut This worked for me some of the time. The pneumatic wrench on its own was not strong enough to loosen anything mildly tight, so don't get visions that I put something on there strong enough to do lug nuts. But in addition to working like a normal human-powered hand ratchet, I feel that the added vibration is enough to help studs that would otherwise break off. > As for the heat/cool method, I plan to use good ole Canned Air. I never tried that with canned air, but it sounds like a pain in the ass since you can go to Radio Shack and for about the same money buy a product made for the job. There isn't much room under there to hold a can upside down anyway. Remember that canned air will turn into phosgene when burned. Don't breath it if you blow it on a glowing stud. Walt Yahoo!
