o2 sensor removal help

Yesterday i built a spacer for my second o2 sensor. when i went to install it, I was unable to remove the o2 sensor from the exhaust. we tried soaking it in PB Blaster (several times), open ended wrench, wrench + extension, socket + impact gun, heating + impact gun, and pretty much everything in between. anyone have a great idea of how to get the stupid thing out? i'm to the point i may just take it to a muffler shop and hope they can get it out without damaging the sensor (though i'm not sure its worth it, might end up costing more $ than it gains me in trade in value)

You'll need a O2 sensor socket and the car needs to be high enough off the ground for adequate leverage.

I ended up taking mine to the local muffler shop (Midas), the guy put my car on the lift, then used a socket wrench with O2 sensor socket and got it off in one try. He didn't charge me anything, you might want to call around, they may do it for free or at least something minimal like $5 or $10.

cool thanks, i had it up on jack stand, with the o2 sensor socket and a snapon 1/2inch drive impact and it didnt budge it at all. i will probably go to the local exhaust shop that did my catback and see if they can get it. sometimes a lift is worth its weight in gold.

A long breaker bar might do the trick too. It worked for me when I did my header.

When I put my header on it took about 20 min to get one of the O2 sensors (lower) off. Had to heat it up with the torch real good.

Personally

I wouldn't use an 02 socket we tried that during my install and rounded it off so we had to buy new one! Which sucks but you can get a bosch sensor cheaper if you reuse your stock harness that one is 71 dollars and it works
