Hi Guys.
I really need help please. I'm in a bad situation and honestly I am out of ideas.
My upstream O2 sensor is stuck. I've watched every YouTube video, read every article and tried every trick I can think of without success. I've tried the following.
Been soaking it with penetrating fluid for two days. Respraying it every hour or two.
Heated up the engine and soaked it again and again.
Map gas torch l... heated bung to over 800 degrees.
Have a very heavy 4 foot breaker bar plus a two foot pipe.
Air hammered the O2 socket to try to break it free.
More fluid drenching.
All the while applying more heat, more fluid, tapping with a hammer to crack it loose. I Air hammered / air chiseled it to try to turn O2 sensor socket. It's hard to get a good bite wort the air chisel but I've hit it fairly well I think.
Tried heating it up and then freezing just the sensor as much as that's possible with CRV. "Freeze off". Tried this cooling and heating process a couple of times whole also drenching it in fluid and heating and trying to crack it while hot.
I'm doing the best I can to keep from rounding off the nut, I still have a decent bite but you can see the edges are starting to get damaged.
My next attempt is going to cut off the sensor with the death wheel down to the nut and attempt to use one of the special sockets used on damaged bolts, lug nuts etc.
I don't don't know if I can get an Angie on it from the wheel well, so that I can use an impact gun or not. I hope so.
The problem is I have to use this car in the morning to get to work. No option to call out and an Uber is over $100 each way and I don't have the money for that.
Does anyone, have ANY other suggestions on what I can try to crack this @&$#%*g thing loose?
I really need help. I'm standing here staring at it and I'm not sure what to try next.
Thank you in advance
