Low oil pressure valve ticking

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 35psi@2500rmp. 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?

I had the truck at precision tune the day before this event. There was a coolant leak. They replaced intake manifold gasket, valve cover gaskets,gooseneck gasket and the fan clutch. I approached them concerning this and they have yet to get back to me. I feel that while the top end was open, something (maybe gunk) dislodged and was sucked over the oil pump screen. Whatever the situation was has left me with normal pressure? AND a tapping in the top end

There's a chance the mechanic did not get a rocker tightened down properly after reinstalling the lower intake. Or.. your lifters, rockers and pushrods are just getting too worn. Happens. Unless you can prove it is something the mechanic did, I doubt they will cooperate much. You haven't mentioned whether you checked your oil, or what weight you are using. If you had a coolant leak, depending where it was at, coolant could have gotten into the oil pan and mixed with the oil... especially if the mechanic didn't drain the coolant out enough to change the lower intake gasket. I know, crazy right? You wouldn't believe what I've seen though. lol
