I had time today to try to get my front o2 sensor out but it wouldnt budge. I had it soaking overnight. I used heat on it. Nothing worked. Now what do i do? I can cut the pipe and then weld in a new piece with a new o2 bung but i rele dont wanna go that route. Any ideas would help.

 

Let it soak a few days

 

What do u suggest using? I used penetrating oil like deep creep kinda stuff.

 

Push comes to shove...take it to a muffler shop and have them replace it (them), if they are willing and able to do it. They have a hoist to get the rig up in the air to work on it and torches they can use to heat the pipes up real good to get them out.

 

I have to check the name on the can but it breaks up rust..... and is a penetrating oil... I will check tomorrow the can is yellow and white I do know that...
