Oil pressure concern Options

[914itis]

My drive to Hershey was flawless. I drive with the newly converted 6 for the first time a total of over 500 miles ov weekend.

The engine sounds great and handles great, however I have a glitch on the oil pressure gauge and light that I would like to figure it out and solved.

When the engine is cold and the car is idling at about 1200, the light is off and the pressure gauge goes up over the 3 mark, as the engine warms up it goes down to 1 at idle and will not go pass the 1 1/2 mark at any rpm as shown on the picture ;the light will come on at a full stop (1000 rpm)
I am using brad Penn 20x50 oil

I am wondering if it's the pressure sender or oil overfill.

All comments appreciated

The motor is 6yl stock 2.0

911s, even the 2 liter engines, run what most non-Porsche people consider scary low oil pressure. When the 2.7 came to market, Porsche changed the oil pressure switch for the light to one with a lower threshold so the light wouldn't come on at idle. At this time, that switch is what you put in all the air cooled 911 engines. If your switch is working correctly and the light comes on at 900 RPM, you're running at less than .5 BAR. That's around 7 PSI. If your temps aren't unusually high, if you're running 20w50, and your idle isn't less than 900 RPM, you may have a problem. First thing I would suggest is installing updated cam tower oil fittings. They're somewhat more restrictive and should raise your overall oil pressure a little. After that, you may have to look into major surgery ......................
