Its normal for gauge pressure to be higher when cold and to drop when hot.
Hows your cooling system holding out?
Is that an OEM in dash gauge? or aftermarket?
Have you tracked the tick using mechanics stethoscope or large screwdriver?
Is this a tick at all rpms or just when idling?
If it is the engine(and not the PS/waterpumps), and only when hot, your oil might be too thin/hot.
Change the thermostat antifreeze belts, and at your next oil change, switch to a 40wt oil. Also try a different oil filter(like purolator/proline).
