Hello new to the site. Got a stumper here!

To me

To 10psi or lower then slowly returns to 30 psi at idle.
Removed lpop and has little scratches on front and back of gerotors
And housing has scratches

No high pressure leaks found when pressure testing

Time to change that pump and the front engine cover it sounds like.

Needs new LPOP and front cover.

I was leaning towards that but just don't understand how it has oil pressure at idle unless it sucks air when off idle

If the pump flutters or cavitates (creates turbulence) at higher RPM it will not be able to move enough fluid.

or you could have a lifter starting to wipe

What can I check with lifter is bad it idles smooth when warm has some Striction on some injectors
