Things that help stubborn parts?

- Heat it up then PB it. (heat sucks it in the threads)
- slightly tighten before loosening
- "tap loosen" the nut, instead of constant pressure.

When I did my PS, I drove home from work, waited 10 mins with the hood up, then PB'ed, sat overnight, hosed it again, then tap broke it loose.

The O2 nut would NOT come off, so I bought a new O2 nut from Nissan, ~$12.

*NOTE*
ANTI-SIEZE that s*** brother ;-)
