Oxygen sensor removal help!!!

Can't get an oxygen sensor out of the cat. Will penetrating oil hurt the sensor?

Thanks

What he said ^^^ and when you get it out put some hi temp anti seize on the threads so you dont have this problem again.

Is it all right for some of the anti seize to smudge on the tip of the o2 sensor?

Doubtful, take a wrag and wipe it off then it should be good.

Just on the threads and don't get it everywhere and you'll be fine.

Thank you guys, this is my first attempt at a header install, I am doing a set of edelbrock shorties (I know about LT's) Everything has gone surprisingly well, I got the o2 sensor out it was a little buggered up (dealership) but I was able to get it back in and solid including the anti sieze. Just waiting for my gasket set for the install. I was going to use anti-seize on the header bolts as well, or should I? I noticed a yellow type powder on the bolts when I took them out. should I use that stuff instead? Thank you for your help.
