Removing stuck O2

[snj111795]

I'm trying to remove my O2 sensors from my rear manifold and downpipe and transfer them to my headers. But as I'm sure you know these things are really stuck in there. Is this more headache than it's worth?

buy a new o2. mine never came out. rusted solid in there, i tried to get it off in the car and no dice, off the car i stripped the nut out.

They're not that bad to get off. Just use the correct O2 sensor socket and some PB blaster or what not. Everyone I've done came right out without any issue.

i had the right socket, it stripped the nut on the sensor. a lot of guys never get it out unless you heat the piss out of it.

Had this issue recently with my wideband. That sucker was in there solid. I was wondering if I was going to the break the welds on the o2 bung. Heat and breaker bar

I have taken them out with the car running to keep things heated up.
