I am a very experienced mechanic - just not with Fords. ASE master tech in the mid 90s while working as a GMC Truck engineer in Pontiac MI.

all the FE's i've had and built. i never....i mean never,.. had any motor under 100k miles have less than 35 lbs of OP at idle unless i had a rod bearing that was on its way out or too much clearance in the cam bearings. if your not finding any component failure then pull the rocker assembly and check for issues, badly worn rocker tips, bent pushrods..... the lash won't be different if you don't mix up the pushrods. thats the easiest to check....if i found nothing.....i would pull the pan and see if the pickup was too close to the bottom( are there any dents in the pan) while it was off i would put one of "pumpbuilders" bluprinted HV
oil pumps in it to be safe. if i found factory rods in the motor, i would pull #7 rod cap and look at the bearing. and based on the total ford components in the heads you will probably find a ford reciprocating assembly
if you believe the 15 psi is ok you will loose your motor. this is not a small chevy. when i race a FE i use high pressure and no less than 80 psi at idle with factory journals is acceptable. 100psi at 3000rpm and up.
The "two schools of thinking" on
oil pressure is right and wrong with ford cranks and rods.
yes, you show the trays in the rocker pic....if you have an audible tick with hydraulic lifters there is an issue....unless someone built this motor and put damn rhodes lifters in...they are noisey...
