I've used the ford spark plug repair kits before. (a LOT of people have!) My dad's "retired" highway truck has blown two spark plugs out in the last year or so. Luckily, it didn't rip the fuel rail open and cause a fire. And still no recall, as far as I've seen.
Ok, so I've decided to replace the head down the road, but figured I'd try a few bubba fixes just for fun.
First off, a guy mentioned pipe dope... Yeah, I thought the same thing, but what could it hurt? Nuthin', that's what. I swabbed the glow plug with the stuff, screwed it in, and let it set for a day. No dice. The stuff is good on plumbing, but not so good for holding engine compression! Now we know, and knowing is half the battle.
Now what's the shadetree mechanic's second best friend? (I couldn't figure out a good way to use #1, duct tape) That's right, it's JB weld. First, I had to clean all the gunk out of the gp hole, then I lightly coated the plug with grease so the epoxy would release when I need to unscrew it. Mix up the goo and blob a thin coat on the threads, then a little thicker around the chamfer where it's supposed to seal in the head. Screw it in until it just barely bottoms out, and let it cure. Once it's good and set up, tighten it down and test fire. BINGO! So far, so good, but I'll need to run it more than I have to see if it holds up.
You know what they say... There's nothing more permanent than a temporary repair.
