YOWZA Posted October 12, 2019 Share Posted October 12, 2019 My 1996 outback barely failed smog so I've decided to change out the sensors, change my oil and plugs and run some “guaranteed to pass smog stuff” I ended up breaking off the rear sensor but its a very clean looking break and can be welded back on the cat. Any ideas on how I can separate the sensor from the cat part? Ive tried heat, ice, wax, pb, etc, etc Link to comment Share on other sites More sharing options...
ocei77 Posted October 12, 2019 Share Posted October 12, 2019 PB or Kroil. Make warm first. vise on O2 bung ( you can buy replacements cheap if needed), and wrench on sensor. O. Link to comment Share on other sites More sharing options...
GeneralDisorder Posted October 13, 2019 Share Posted October 13, 2019 Buy a new bung. They are cheap. Link to comment Share on other sites More sharing options...
Rampage Posted October 13, 2019 Share Posted October 13, 2019 On the floor, I put the bung into a pipe wrench facing up, slide a box wrench onto the sensor. Put a piece of wood under the wrench to make it set level. Get the wrench tight and tap it with a hammer. The shock will loosen it and then it usually turns off by hand.

YOWZA Posted October 13, 2019 Author Share Posted October 13, 2019 CowaBUNGa!! Mission accomplished. After working on it for half the day, I became frustrated and reached out for help and sure enough soon afterwards it busted loose. I think i tried all your suggestions and not sure which one worked, but I appreciate your help. thanks Link to comment Share on other sites More sharing options...
Rampage Posted October 13, 2019 Share Posted October 13, 2019 Great... It's a shame something so simple has to be so hard, but it's a great feeling when it's done. Link to comment Share on other sites More sharing options...
