passenger side O2 sensor removal!

Any hints for removing the O2 sensor on the right (passenger) side? The O2's bolt shoulder is almost touching the transmission case. I don't have an o2 tool, but I do have a nice crowsfoot flare socket that works fine most of the time. Surely you don't have to remove the right side exhaust manifold?

Thanks,

The O2 socket if you had one will slip over.

I’ll go buy one. You mean the long deep well 7/8 socket with the slit in it? I sure hope the walls are thin. The bolt shoulder is almost touching the tranny case.

Yeah that one. If no, try a wrench? The manifold has always stayed in place for me.

Are you removing the o2 sensor for the sole purpose of replacing it or is it for some other reason and your planning to reinstall it afterwards?? If you're doing it to replace the o2 and you were planning to throw the old o2 out,you can simply reach up into the tunnel area where the converter sits and cut the o2 sensor wire pigtail with a pair of cutters.Now you can either slip a box end wrench over the wire bundle & slide it up & onto the o2 sensor nut or you could use a regular deep well socket too,without the slit in it,since you cut the wires close to the o2 sensor body,so that a regular deep well will fit over the wire end of the sensor with the wires cut.You wont be able to use this method when installing the new o2 because the wires will have to be left intact.Theres been a few times where Ive had to pry on the hpipe then wedge something between the pipe & the underside of the car,so enough room could be created for removal of the sensor.If prying wont allow enough room, you may be able to access & loosen the two nuts that attach the hpipe to the manifold so that it will have some movement to get the hpipe away from the transmission enough so that the bolt shoulder wont be touching anything and the o2 will come out easily.A impact gun or torque wrench is sometimes needed to remove those two nuts.
