It's a bit cold, so I haven't done much driving. IIRC, oil pressure gauge indicates 50-60 PSI idle. It's about 90 on a cold start. I don't think I have a thermostat for the oil cooler, so it's slow to warm up the oil. The noise recorded from the video was after driving home from work, so the engine is warm. The loudness of the noise appears to be the same with a cold or warm engine.
The oil I'm using is Mobile 1 synthetic, and that's what I'm using now after getting the turbos installed last year.
Edit, possibly injector ticking. I just started noticing it recently, and the ticking sometimes numbs my brain. It's a weird feeling haha.
