Message Like the others are saying, applying PB over time can help. Remember to tap the stuck parts to vibrate the lubricant in there. I had to retreat over the course of several days to get the driver's side O2 free. The passenger O2 froze to the bung and the O2+bung came out of the downpipe rather than just the O2. Had to buy a new bung, but that was no biggie. The downpipe was fine.

If you keep wrecking O2 wrenches, at some point you might cut the O2 cable and use a regular deep socket. Check fitment, but as I recall this is what I did for the passenger side. It was a long time ago.
