Next I started on the 02 sensor install. I run a crankcase evac setup on my driver and passenger side so I decided I needed to remove the evac setup on my passenger side. I don't use the passenger side evac so I decided that would be the best to remove
Next I chopped off the insert then drilled out the remaining hole. This job was not fun but very critical. Now I'm ready to install the 02 bung and weld it in.
