O2 sensor ?*
To those who have replaced the oxygen sensor, I have a couple of questions.
1. Did you presoak the threads with something like PB Blaster and if so, how many days did it take?
2. Were you able to get it from the bottom or the top?
3. Finally, Is there a special tool required?
Thanks in advance for any help.

I did not need to presoak it to get it off. It helps, although is not necessary, if the engine is slightly warm. I got to it from the top, with a couple of extensions. I have a special socket for removing the sensor which can be borrowed from places like Autozone. It makes the removal a lot easier, although it is possible to remove it without it.

When I did mine a few months ago no PB blaster or liquid wrench was used. The O2 looked like the orignal one and it broke free with very little effort. I was able to get at the sensor from the top but I'm not sure if the 00+'* have more or less room to work with. But I used a crows foot with a extension bar and it couldn't have been easier.

I replaced my brother'* O2 this summer out of his 270k mile 92 SE. He had never replaced it, since buying it with about 100k, so who knows how long it was in there. A decent shot of WD-40, had a snack, ran the car for about a minute, and it came out without trouble.

I think the question was as in following his procedure to the T. Did he have a couple warm homemade chocolate chip cookies with milk, or did he have a pickle and cream cheese sandwich.
