Oil Pressure Concern?

Hey guys. I've noticed that since about yesterday, my oil pressure reading is looking rather low from what it is usually.

I'm not getting the warning light, however, it's sitting within the closer half to the 0 and first mark point on idle (warm engine), and it's not moving much when revs climb (even up to 4-5k RPM). I only notice this difference now because previously the reading moves a fair bit with different revs, and it's certainly obviously higher pressure at a cold start, but it doesn't seem to be reading near the same now?

I have checked for any leaks, oil level is fine (checked 4H after the engine was last run). Oil temps are normal too. Apparently the stock gauge is not super accurate, so should this not be trusted? I'm not noticing any other issues when driving either.

My current setup is:

New R33 crank (not sure if worth mentioning), N1 Oil Pump, a stock sump with a Tomei baffle plates and a Tomei 1.5mm restrictor to the head.

Your advice is appreciated - I am a bit paranoid about this, since my motor spun a bearing last year, and I've spent quite a fair bit on my new setup (only 3 months old).

Cheers!

Get it checked ASAP either way, i wouldn't be driving it personally with a built motor as well... get it towed - sensor checked/replaced and go from there.

Wont hurt to change it or put something aftermarket on anyhow

      While doing my tailgate struts I found some rust. Also replaced my bonnet struts. Such a cool satisfaction with that job.

      Should I use rust converter on this?

      By PranK · Posted

      So I removed as much as I could from both sides. The shop vac did a great job of clearing 99% of it. I got it all as clean as I could and then absolutely drenched the whole lot in the rust converter. Tonight or tomorrow I'll hammer it again. The cavity must be close to 400mm in length and surprisingly I was able to get it right to the back.  I'll quickly reassemble and then pretend I never saw it. I'll post pics (for me to ignore later) soon.

      Help Understand GTT Boost Setup

      I have always resisted the urge to go silly. 8" wide wheels and street friendly spring rates? Check. (Let's not talk about the steadily increasing spread of spherical joints across my suspension!!) Stock turbo, run at 12 psi? Check. Lasted for~?10 years before it died. Highflow put on rather than seizing the opportunity to go G45. You don't need 300 rwkW, let alone the more massive numbers that seem to be essential these days, to have a car that is already way too powerful and fast for a streeter. ~250rwkW is fine. I've never exceeded 200, although I will sneak up above it if and when I manage to get my finger out and do what needs to be done to use the highflow's capacity. You don't need $10k worth of CF bits glued onto the outside. You don't need razor sharp ankle cutting front splitters. You don't need the car to be 2" off the ground. You don't need flawless paint, mirror finished wheels, brand new indicator lenses, etc etc. All these things just make the car impractical and will cause you pain when they get damaged, which is inevitable for a street car. A few nice additions are good. Good seats are good. A nice stereo is good. A/C is good! (46° on the road yesterday and my A/C is degassed again. Was moderately traumatic driving home!) The main reason I stick with a mildly modified old Skyline is that I have had it for >25 years, the mods are the rolling result of 25 years of things dying and being upgraded opportunistically, coupled with a few "just 'coz" ones. And I hate almost all modern cars. If I was a young buck starting out now.... I wouldn't bother. Cars have a few years left where there is any possibility of interest or fun. Thereafter there will be no such thing allowed or possible. Any time, money and effort spent now on a project would just be a waste.
