How to change the O2 sensor on bank 2

I was underneath and it looks impossible to even reach it. I could pobably get the 7/8 wrench on it from underneath, but no way am I going to be able to get an arm in there to start the threads.

Please help. Runnin' with one new O2 sensor.

I soaked it for a couple of days with PB Blaster and then somehow managed to squeeze my arm in there and got it out with a stubby open end wrench.

If you have a dual cat car, take off the drivers side portion of the y-pipe. That will allow you to get up in there. Might as well change out the #8 plug because that is right there too!

I have a 93 which is a single cat. Driver's side was a breeze...

I have headers, but not the time and I don't know which I'm going to do. True duals, catback, etc.

In the meantime I might take a chainsaw and clear the way to the DS O2.
