Ok, so heres the deal. I have a frozen o2 sensor in my downpipe i can't get lose. I've tried heating it with a propane torch and loosening it with two wrenches camel-backed on to each other and nothing. The thing won't budge. Anyone have any ideas? Thanks.

 

Have you tried letting it soak a few days with good penetrating oil? Maybe a combination of heat and oil may get it loose.

Watched a video of a shop using heat and candle wax to get stuck exhaust manifold bolts out.

 

Soak it for a few days.. Get an o2 socket and throw a ratchet on there with a cheater bar.. they come loose.

 

i've soaked it a little a couple days back but nothing. I just got the new one in the mail today and i feel like this **** one is never coming out

 

Thats what I thought to.. A wrench isnt the best thing.. Thats why I went and bought an o2 socket.. Made quick work of it
