So, I looked up the normal pressures in the workshop manual. Here is what I found. Today I was working my machine pretty hard in some pretty severe heat and humidity. At 1800-2100 RPM I was running a shade over 30 PSI. IDK the accuracy of my gauge (even though it's an AutoMeter). Oddly, whether it's idling or running at a little speed it really doesn't change. So IDK how normal or not that is. Engine has just over 1000 hours, has had either Amsoil 10-30 diesel oil or Rotella T6 5W-40 (which is currently in it).
So I guess everything is healthy
