Stuck O2 sensor
I've PB blasted the hell out of it, and done warm and cold cycles and gave it some love taps with a hammer. Still stuck. Any other suggestions??

Good luck...I was getting pissed after cranking on it for 2 hrs, I put the torch on the pipe for like 2 mins and it came right out...I put anti-seize on the new one when I put it back in

thats what I thought too! But it turned out ok cause all the ceramic came off with the part that snapped, so it was a pretty straightforward removal. I was about to fall over when we first did it, though. In that first moment of panic I was pretty sure I now had spark plug in my block... But it was success in the end.

I've never had a problem on any car,truck,etc when you break it loose when your exhaust is still hot. Anyways you should be heating the bung not the o2 sensor , heating the 02 sensor will only expand the 02 sensor and that isnt what you want.

Also be careful putting on anymore neversieze on the o2 sensor because any antisieze in the wrong spot can kill it fast,plus they already come with it applied from the factory, just a warning for everyone.
