the oil pressure hole thread is 1/4 NPTF. It is a tapered thread dry seal so you are right not to use thread sealant. Mine doesnt leak and it is very
tight.

Are you sure it's leaking from the threads , when oil pressure switches leak it's normally knackered . fit a new switch with no sealant on
threads , should cure the leak .

Also make sure that the threads are REALLY clean - NPTF seals because of the shape of the threads on the male and female don't quite match
(deliberately!) so they jam up against each other when tightened into the taper. A bit of tough dirt may spoil the seal.
