Re: 2004 Vortec 5.3 Oil Pressure Sending Unit?

I have looked at the unit every which way, and cannot get to it without removing some of the cables, harnesses, etc, that are in the way. I also looked at the PVC valve and tried to remove it - it acts like it was installed with a hydraulic ram! I even tried using pliers to pull it out of the seat. Nothing doing.
