Help with o2 sensor removal... As a part of my continued restoration, I purchased some new o2 sensors this weekend. The car is a 95 formula, so it has two upstream sensors. The driver's side was a piece of cake, but the passenger side has turned into a job in itself.
What I have tried:
1. Adjustable wrench. Multiple angles, flipping the wrench, no go.
2. Unbolted the starter for more room. Helped to get more leverage, but still, no go.
3. Using a screwdriver with the above wrench, for more leverage, no go.
4. Went out and bought an o2 sensor socket. Used a breaker bar, no go.
5. Used a metal bar (somewhat flimsy, didn't help a lot, but helped apply more torque) No go.
6. Started the engine, let it run up to operating temperature. Shut the engine off, let the pipes cool down a little, since their is a lot of exhaust in the way. Didn't seem to help.
I can't get this thing to budge. It's almost like it was welded in. (it's not by the way)
Any ideas or tips?

Go to an autostore and rent an O2 socket it makes your life waaaay easier. Had the same problem with you and tried everything then i got that o2 sensor and got it off in 30 seconds. haha get one
Did you spray the hell out of it with PB Lube, or Liquid Wrech, or WD-40. Do that and let it soak for about a hour. then attempt to get it out and give some more spray too. It is the rust that is holding it...

Yeah, thanks 7901ws6, that's what I'm going to try next. Other than that, I'll have to take it to a exhaust shop I think. If PB can't loosen it up, it'll have to be heated. I don't have the proper tools to do it. If I put much more torque on it than I am now, I'm afraid I'll damage the exhaust pipe or bung. Thanks for the help.

I had a hard time getting one of mine off...used a torch and heated it up around the threads on the sensors and where it goes into the exhaust tube. Get it good and hot then hit it with a wrench....worked for me. Be aware where your fuel lines are when doing this.
Good Luck!
