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

Can't speak for the oil light, but on flat sixes up to the 3.0L, the gauge was a 10 Bar (140 psig). Using a 10 Bar sender with a 5 Bar gauge might not work really well. Maybe you have a gauge / sender mismatch.

My gauge shows 0 at hot idle, but my oil light does not come on.

Overfilling will not cause a reduction in oil pressure. It will cause oil to be blown out of the tank thru the vent.

On cold startup, my engine throws 100+ psig at 2K RPM, but then settles down to about 10 psig per 1000 RPM.

Electrical gauges are subject to 40 year old wiring connections. I would buy a cheap mechanical gauge and plumb it in to verify your gauge readings.

The above was my first thought ...

If you've got the right parts, sometimes they do go bad, so you can try swapping them out if you (or a budd) happen to have a spare.

Also make sure your ground is good.

Oil pressure is a really important thing to have right, so do figure it out before you run the engine much.

I Agee you should figure this out.
What are the motor compression numbers and mileage.
Definitely worth trying the senders too
