Or, grab some map gas and a good vice grip or a plumbers wrench. heat up the bung (concentrate on the bung not the sensor and turn it orange ( the sensor will also be a dull orange. Then turn it out. ( have fire equipment handy.) Or - buy a cheap 7/8 or 22mm socket and weld it onto the sensor in a few spots. Let the heat soak in while welding. Then turn it out

Thanks for the advice. I have no welding tools. I could try the map gas to heat up the "bung". What is this "bung", BTW ?

Thanks.

Bung is the piece of metal that has the threads for the O2 sensor to screw into. The bung is welded to the pipe so you can insert the O2 sensor into it.

buy/borrow a mapp gas torch+vice grips

you want to heat up the exhaust pipe around the o2 sensor(the aforementioned bung and surrounding area) until it glows red(usually takes about ~30 seconds)

I have mapp gas torch and vice grips. Definitely give it a try. Thanks.
