Alright thanks for that info. I'll just keep an eye on it and if the light comes on ill make a move from there.

I bought the car only a few months ago with high kms so im keeping my eye on anything and everything and keep on top of it all. (Hence my concern)

I'm having a similar problem, my car has 150,000 and each day the car is running less pressure (went from 3.5 to 2 to 1.5 and this morning i noticed it on 1) I'm pretty concerned about something damaging like oil pump especially since the high km's.

I read above that its probably the gauge but will the gauge still read okay only lower? When i boost it moves up to 4 on the gauge but on idle or cruise it will drop again.

hey mate, wondering what your outcome was, i'm having the same issue at the moment with pressure dipping to 1 on idle sometimes.

Thread revival but better than starting another.

Mines just started doing the same. However coincidentally happened after I changed from Nulon 10W-40 to HPR 10-50w, but also resoldered tacho. I double checked oil level and also tried re-cleaning all terminals on the flexible cluster PCB.

Went from 0.5kg/cm idle and ~3.5-4@highway cruise pre oil change and cluster work too

  ~1.5kg/cm at idle to  2.5-3kg/cm at cruise

I can't imagine this could be just the oil and potentially noticing more after doing a few changes.

Has anyone tried Fuelmiser CPS141 oil pressure sensor. It's about half the cost of the stupid OEM cost.

Cheers

      Original window sticker?

      By Celticsfan03 · Posted

      Hey everyone. Is there a way I can get the original window sticker (maroney label) for my 1995 R33 GTST? I doubt I’ll be able to ever get it but it’s worth a shot to ask

      It was a great, but typical track day, and some VB was ingested at the night time debrief 🤪

      And so, to round this out, I couldn't be happier to confirm @MBS206 has decided to buy the car. He drove down from sunny QLD with a trailer last week and it is off to its new home today. I'll let Matt confirm on next steps but I understand broadly that the plan is to leave it pretty much as is, and just get some quality wheel time with a nicely balanced car that is pretty much track ready. There are a few a jobs still to be done first but nothing too major and I think its a very smart buy Dinner last night at the Paragon with a round of VBs (mostly) for Neil

      Well, 50 pages and the end of a chapter for this car. We took it out for a shakedown at Wakie yesterday, and everything went well. There were a couple of niggles: - Oil cooler fitting leak - tightened, cleaned, stopped leaking - Radiator cap overflow fitting was leaking....Mark called it, the overflow fitting was threaded in and not tight....tightened, tested and held pressure - Small oil leak at the rear of the block, probably the turbo oil feed - too hot to get at it comfortably but probably just needs to be nipped up - leak at the driver's side rear brake line where it meets the hardline. Fitting wasn't loose, so Matt backed it off and back on, no further leaks - there's also a leak somewhere on the top of the fuel tank, maybe that cross over fuel line - that was has been left to fix when its on a hoist Otherwise than those niggles the car went great, turned great and stopped great so it was a very successful day out. I'm always really nervous when a car first hits the track after a long break, especially with a brand new engine as well but it was great. VID-20251011-WA0007.mp4  Big thanks to @The Bogan who dropped by and helped out, @MBS206 and my nephew Lachlan the apprentice.  Neil's wife Mel also surprised the hell out of all of us by dropping by; she's up in Tamworth these days but was travelling to Melbourne so had plausible deniability for turning up at the garage, it was great to see her but also obviously a bit sad all round.
