I was working on the 92’ Vette and the passenger side O2 sensor was being stubborn. I couldn’t remove it with the tools I had available. This particular sensor is mounted onto the manifold and in a position where basic sockets, open end, crows foot and even a standard O2 7/8” or 22mm tool could not access.

The drivers side sensor was a bitch to remove but the passenger side I couldn’t get to. I ordered another O2 sensor removal tool that is designed to work with hard to access manifold mounted sensors.

I’m hoping the additional length will provide the angle needed to remove the sensor. I’m thinking a 3/8 extension and a pry bar will get it. I already sprayed the parts with PB Blaster.
