impossible to remove 2nd oxygen sensor

I have the DP off, and I need to transfer the second 02 sensor back to my stock DP.

I have soaked it in liquid wrench probably 10 times in the last two days. I tried a wrech, a ratchet with 02 socket, moved to a longer ratchet for more leverage, sprayed more liquid wrench....

it just will not even begin to budge.

any ideas before I just order a new one and sell the DP with an 02 sensor in it??

More elbow grease should work. Also try putting it in a vise using an wrench w/ a hammer.

Stick a pipe over the end of the wrench or the ratchet for more leverage.

home depot has propane torches for about $30, and they are always handy to have around.

What I have don is to stock the 02 sensor in my bench vise and use the downpipe as the "wrench" always worked well for me.

agreed, and you have got to put some heat into it.

I ruined an 02 sensor about 3 weeks ago trying to extract it from a downpipe it was just totally seized into. ended up ripping out the 02 sensors threads, and got it to just spin, and it still would not come out! So it might not be too bad of an idea to just give up if you have it in a vice with a 4 foot breaker bar on there and it still won't move.

I second the motion for a vise. Put the O sensor in the vise and turn the dp. Leverage is your friend. Heat will help too, but you have to get it pretty hot to do any good.
Let this be a reminder. When you install a new O2 sensor or swap it to your new DP, use a little never seize.

mcrowley's advise is good. i do that all the time with seized lug nuts on my c900 wheels. and when it FINALLY comes loose, there's gonna be this big bang from the pipe hitting against the ratchet... its fun, dont hurt urself...

Eh it worked. I brought the downpipe in with the rear o2 sensor in it still. Sensor was fine and it still works.
