2000 GTS

Hello All, started noticing a ticking noise on passenger side of the engine closest to the firewall. Noise is there only when the engine (not just the coolant) warms up after driving for a while, using the stethoscope seems that ticking is loudest on the two last bolts of the valve cover (closes to the firewall, top and bottom bolt). I can also hear the noise from the cabin at times again, passenger side. Unfortunately not sure if there was noise there before the oil change.

1. Car has ~20K on it, clean, no leaks nothing like that
2. Had my oil changed not so far back (Mobil1 10W-30 Synthetic with Mopar oil filter).
3. Oil level is at a “full” mark.
4. Oil pressure always reads 60 occasionally moving to 70 psi. I’ve never seen it below 60 even at idle.
5. Popped the valve cover off and “shook” the rockers all seem to be having the same side to side play but all are consistent with each other. Tried pushing down on the rods they are not moving down.
Questions:
1. Any idea on the “ticking” is that normal?
2. Any idea on the oil PSI never dropping below 60 PSI? Is that normal?
Thank you!
