Re: How hard is the o2 sensor screwed on there?
I used a table vise and lots of PB Blaster and a breaker bar to get a seized O2 out once. Instead of unseizing it just ripped all of the threads out of the manifold leaving a somewhat clean threadless hole

just get the one that is 1/2 socket and use a breaker bar and that O2 sensor should be out in no time.

How can you not get it off or at least break it?
I have broken a couple of them, it isn't very hard.
If I know I am gonna take mine out, I just start spraying it with WD-40 or PB blaster a couple days ahead, each day. It soaks in well and is like butter comming out. there after.

It's not coming out, I let it soak for 2 days already, with a bunch of wd40 each few hours. It's not because I don't have enough force on it, I'm using a 36inch breaker bar, and I don't want to stripe all the threads out. How do I un-seized this thing, and what the hell does seized mean?

seized means its fused to something. so, to unseize it, heat it up with a torch like you were told before. Just heat the lug of the sensor, not the manifold. when (or if) you get it out, when you go to put the new sensor in, coat the threads with antiseize, dont get any on the end of the probe. goodluck.

try a can of thrust. i found that to work better than wd and pb blaster.
get a torch and evenly torch the entire nut till its really really really really fuggin hott. (hot metal expands) then get a pipe wrench and slip a longer bar on there like a 6ft or somethin and just twist it out
