I was trying to get the O2 sensor off the O2 housing and despite the PB Blaster and the Heat, it was not coming off. Eventually I took the whole thing out and got it out with a breaker bar.

My question is this, some PB Blaster got onto the O2 sensor when this was happening. Is this a problem? Will I need a new O2 sensor? I would prefer to know this before I put the car back together and find out it won't run right because the PB Blaster screwed up O2 sensor.

Thanks!

 

+1 . I'm in the same hole. I'm planning to reinstall mines this weekend.

 

It should be fine once it runs for a few minutes. I've used carb cleaner to clean em before and literally soaked em. And they idled like crap for a few minutes and then ran normal. Until the sensor went completely out. Unfortunately for me pb blaster and heat got the o2 sensor out but stripped the threads so I had to buy a new one. On top of that I broke a bolt in the housing proceeded to drill a hole and use an ez out and broke that off in there as well so I have bigger problems with my o2 housing now, I've been trying to swap manifolds and o2 housings for a week now this **** sucks lol
