Yes, Im offically an idiot or bad luck follows me.
Sunday I put my old Y-pipe on the Max to pass emisions.
Today->went and fast passed the emmisions, then i went to re-install the Budget y pipe.
The 2 O2 sensors were both stuck and still are.
I disconnected the wires and pulled the y pipe out but still I Cannot Budge the O2 sensors at ALL.. I even tried to spray em down with Liquid wrench, I tap welded the wrench to one but still they wont come off. At All. Btw, i just replaced these both 3 months ago.



Can someone show me the cheapest place to buy new O2 sensors.
thankyou.

 

there that tight ? did you try using a breaker bar?

 

yeah i tried. i used a huge cresent wrench and rounded one of the sensors off.

 

Heat is what helps makes them stick, and heat will help to get them off. PB Blaster or S'OK (both very good penetrating fluids) can help. I've noticed that Liquid Wrench isn't nearly as effective as PB or S'OK.
Did you use antiseize when you put them in? Make sure you do in the future.
