Spray it down with PB blast, let it sit for an hour and work the bolt both ways, back and forth until it lets loose. Don't reef on it, equal even pressure with a half inch drive socket wrench should do it...

WalMart should have it, Its what Jeep guys and hardcore off-roaders use to loosen up bolts that have been subject to extreme punishment (suspension, etc). Should be in the same section as WD40, just works better.

well... any luck?

Well, I guess if you can't get enough torque out of the half inch drive, its probably screwed up enough that you're going to have to replace the plug anyway... ski poles w/o the rubber grip make great breaker bars if you have room

I've seen the PB blast work wonders when left sit. My buddy had satan-spawn bolts on the lower control arms of his cherokee. After soaking the bolts for three days (two applications per day), we went to remove them they were off and new control arms bolted up in 30 minutes. I would give the plug another spray, let it sit overnight, spray it again in the morning, and use an impact wrench with your firiend's air compressor. You've got the right idea waiting for airtools. sorry to hear its puting up such a fight.

yep, you should be turning it counter clockwise when looking up at it from under the vehicle. If the wrench is on the plug and handle is pointed at the driver's side rocker panel, (12 o'clock is the muffler, 3 o'clock is thee passenger side, 6 is the headlights and 9 is the driver's side) you should be turning it from the driver's side through 6 o'clock towards the passenger side rocker panel.
