I couldn't get it out with just PB and a box wrench. I blasted it about four times with PB over three days, warmed it up a bit and got it off with a crows foot o2 sensor wrench. No more problem, plus it was easier to tighten down with the crows foot.

Good luck.

Torch it if you have too. Hit around the threads really well. I sprayed mine with pb drove for about 30 min and hit with the breaker bar. It came right out buy I burnt the he'll out of my arm. Thought it was goons be tough so I really torqued on it. When it loosened right up my hand slipped off my arm went up on the oil pan. 6 weeks later it's still scabbed. Anyways yeah get a propane torch if your still having trouble.

Cherry out the pipe all around the nut with a propane torch. And then use a long wrench.
