Ford Spark Plug Problems?

Clouddriver, that gap tool is a nice one. It's one of the best I think. I have a bunch of different ones and that one does the gap and adjustment very nicely. For a less expensive setup than the Snap-On socket, it's possible to get an extension and socket that lock together with a pin that has a spring underneath it, similar to impact sockets. I can't remember the brand, but just make sure it can't come apart. If the socket jams, a magnet may not be strong enough to get it out. I do think your duct tape idea will work unless it jams really bad, which I think unlikely. The Snap-On socket is a 3/8 drive and it fits the plug perfectly. The B diameter you mention is not more wide than usual, in fact I think it to be more narrow which is an advantage. You can kind of gently feel the plug drop into position with a slight wiggle of the socket then very slowly start to turn it. If it hangs up you stop, alter the angle a bit, then turn repeat. Be gentle. Once it starts you will feel uniform slight but smooth resistance and you know your headed home.
