2003 TJ 2.4L 5spd. Bought used, 166k mileage, performing maintenance, and have discovered a problem. The #1 plug will not come out. The rest of the plugs were not too much of a problem, but came out clean. From the looks of things, the plugs were in a long time and anti-seize was not used. What is it going to take to remove that #1 plug?
Seized spark plug?

Is it not even braking loose, or does it start to thread out then stop?
Have you tried using some penetrating oil, like PB Blaster or Kroil? There could be sufficient carbon buildup on the end of the plug threads jamming things up.
PB-Blaster is barely better than WD40 that isn't even a penetrant. Liquid Wrench, Kroil, and Break-Free are all significantly better choices than PB-Blaster.
As gently as possible try to go back in with it and then back out even if its less than a few degrees of twist. Keep it soaked as well. This typically works on corroded, galled threads.
Try tightening slightly then go the other direction in small increments and work it back and forth while shooting your favorite penetrant oil in the hole
Thanks for your opinion Jerry, next time maybe try not to be so condescending. Don't forget, sometimes the shit you want everyone to like because you say so... isn't necessarily readily available in their neck of the woods.
Penetrating spray, which includes WD PB, and all others mentioned would have NO issue getting past the loosened threads to soak into any carbon build up on the end of the plug...

I really don't think he was trying to come across in a condescending manner. I know @Jerry Bransford has a general dislike of PB Blaster as he has mentioned it several times.
I've used PB Blaster for years and it really in nothing great, but that's what our shop used. There are better options out there.
There one purpose that PB Blaster is really useful for is MACE. I keep a can of it in all my vehicles.
I'm not sure if you have ever experienced getting PB Blaster in your eyes, but holy mother of God, the shit burns like hell.
As for removing the spark, If the OP doesn't have access to a good penetrating oil, I would soak it with Seafoam or a solvent that will dissolve the carbon build up on the threads.

If you think expressing a personal opinion on which penetrants are the best means condescending then have at it. There are several good Youtube videos on penetrant tests like this one from Farm Project and PB-Blaster didn't do well as well as the others on them.
This. This is the trick to removing rusty bolts. Most people lose patience and don't want to keep turning it backward. It feels counterproductive. I settled on the belief being willing to go slowly back and forth takes less time, and trouble, than drilling out the bolt after you break it. I have a PHD in drilling out broken bolts.
I didn't say "out in the sticks", boog.The OP @Barley lives in the big city.
Neck of the woods = a particular area or locality.
Nor should it have been.
Walmart sells Liquid Wrench. They even have a Walmart in the boonies.
