[TR] TR3A oil pressure

[DLylis at aol.com]

My (formerly) newly rebuilt 3A motor has excellent oil pressure.  My  gauge 
read 65 lbs at idle upon startup and ran about 80 lbs driving.  Warm  motor 
idle was at 50 lbs. Twice now, the pressure has dropped to 20 -30 at idle  and 
shutting off the car and waiting returns it to the previous readings.   The 
driving pressure is as before.  Stuck pressure relief, you say. I  agree, so it 
removed it and cleaned it and all seemed well. Something odd  happened, however, 
which is counter intuitive.  Now, as the motor warms up  to operating temp, 
the pressure increases to 70 at idle and 85  driving.    I questioned the gauge 
so I changed it for  a SunPro and I get the same readings.  I have a spin on 
adapter and an  oil cooler on this car. 
I know the pressure is high and intend to adjust the pressure relief once I  
see what makes sense here.
 
Thoughts?
