Heres what my 02 sensor looks like at 211K
First I'll say I hate anything exhaust related. I was afraid I would break it trying to get it out. So I sprayed it with WD-40 this morning and again when I left work. Then again before I pulled it. Surprisingly (to me) it came out with no effort. I did how ever buy the 02 sensor socket and that made getting at it easy using two extensions one swivel socket and a torque wrench.
What do you think? The threads are dark from the WD-40. To me it looks pretty good for as old as it is. I'm not saying I'm saving it to use later. I just thought it would have looked a lot worse.
