It depends on how you treat them and what oil you use as well.A couple of well placed baffle plates will completely remove oil surge from the engine.
The ca18det was never any good if run on crappy 10w40 either,Mobil 15w50 will make it last a lot longer.
Anyway,there is more Nissan knowledge your little toe than in that tools whole body.If your man wants a proper job done then he will give it to you and not to mr classic car with his sheepercharger,or sorry I meant supercharger.
