Most Z32's with any milage have ticking lifters...
and the oil pressure gauage is notorious for being low...

You can change out the oil pressure gauage or take it off and put a drill but the size of the oil hole down in it turn it a few turns by hand not pressing.. That usually that's out the crude and inproves your oil pressure
The lifters and engine can be rejuvenated by running seafoam in the crankcase and fuel tank a couple of times.

Just rebuild them
Ash has a write up on it.

As for the pressure, the oem gauge and sending are crap. Go aftermarket. Seafoam is a good idea
