MLCMK Posted August 16, 2016 Share Posted August 16, 2016 Hi all Anyone know if the rear 02 sensor (the one current stuck solid in my de-cat) on a 2003 350z is a normal or reverse thread? Tried giving it a good spray with WD40 etc but it's stuck in the de-cat good and proper. Any hints or tips on how to get it out or is it just a case of brute force and ignorance!

GT Driver Posted August 16, 2016 Share Posted August 16, 2016 (edited) Breaker bar ftw! Try using actual penetrating fluid. WD40 is only good for water displacement and in itself is not a lubricant. Apply penetrating oil - leave for an hour or so and try again. If no luck then, apply some more penetrating fluid and leave overnight.
