<VV> Oil pressure

[PETER INMAN]

I guess the question is at engine hot after a 3 mile hike up and down hills the engine is definately warm, not smokeing hot but well warmed up. This is when I notice low oil pressure at low rpm. I just started it for the morning and both guages (electrical and mechanical) check 45/50 Lbs at idle. Thats what I always had just pokeing around the yard never really getting it warm. I have the raised pressure spring from Clarks installe. Starting to rethink spring to original. Should cold verses hot have that much effect on pressure. At warm oil temp at 2000 rpm the pressure checks around 40, verses 60 at start up tempiture. Anything else please let me know. After so many years of getting this ready I`m so paranoid. Pete

5-15 at hot idle seems normal.   Anything pressure that keeps the lifters pumped up  and the light off is fine!

Use the "uncalibrated"  electrical gauge as a reference!  Like our head temp gauges...if you see a change from "normal"  then worry!
