I use this stuff (Anti-Seize) all the time. Especially on exhaust components where I KNOW that one day, I'll be doing this job again. You're right, it does make it much easier to remove the bolts(or sensor) the next time.

My Bosch O2 didn't have the coumpound on it, but when it failed 30 days later, the AC Delco replacement did.

I also used an adjustable wrench. No problem.

I've done this before. I may look into it this time as well.
If the anti-sieze is on my new O2 sensor I will just run with that. The stuff that'* on it will probably be the best for that sensor anyway.

Don't forget to check the FPR. If the diaphram is ruptured, it will leak unmetered fuel into the intake.

Had to ask: what is the best way to check one'* FPR [short of swapping it out for a new one] on a '93 SE?

Pull the vacuum line off the FPR. If any gas leaks out, your FPR has failed, and needs to be replaced ASAP.

EDIT:
Does that last sentence remind anybody of PBR me ASAP? Just noticed that...

Ive heard the easiest way is to run the car for awhile til its warm....and then remove the sensor...the heat warms up the threads and makes removal easier...but dont burn yourself!
