From experience I can tell you that oil filters are not bi-directional.
In on the perimeter.
Out in center.

The engine appeared to be running fine before I shut it down. I checked the wire to the back of the engine monitor and all was fine. I also checked the continutiy of the wire to the sensor and it was good. I started the engine again and it started fine and seem to run fine, however, the OP did not kick in so I shut it down again
