and for my part, the resolution was oil pressure over 20 PSI idle hot. Pressure at 1500 RPM was 42 PSI. Anything between 20 and 45 PSI at 1500 RPM is good. That means, the reason why my light is coming on is likely due to a faulty sender.
The factory oil pressure switch is fairly difficult to get to. I accessed it from the front under the car and it was basically by touch only. Put your hand on the oil dipstick tube and then follow that down until it goes into the block at that point your fingers should pretty much be touching the sender I used a quarter inch drive ratchet with a deep socket on it and it was basically one or two clicks at a time. as was stated earlier, my sender was stripped and would not unscrew, so that means I need to find a new location.
