Stuck O2 sensor 200,000 miles on a 89 burb

PB Blaster, PB Blaster, maybe a 3rd day of PB Blaster, drive it to get it good and hot, then more PB and pull it out hot

If it’s no good and going to be replaced, cut the end off then put a normal socket on it and try that.

If there is room, try getting in there with a mini pipe wrench. Or maybe a basin nut wrench.

My O2 sensor tool is a 7/8" 6-point box end wrench, works much better if space permits. Goop up the new one with anti-seize.
