Low oil pressure valve ticking

Just bought 2000 Ranger with 123k miles and lifter noise. I have hooked up mechanical guage and the oil pressure starts at 50 psi at idl. After running for half an hour I'm at 14psi at idle and [email protected] Fresh 5w30 with filter.

What is the oil pressure supposed to be at operating temp at idle?

What would be my next step in troubleshooting process?

haynes manual says for a 3.0l it should be 40 - 60 PSI @ 2500 RPM, for a 2.3l and 4.0L it should be 40 - 60 PSI @ 2000 RPM.
