Hi guys,

I'm after a bit of advice, I have an r32 gts-t (93), I have noticed my factory oil pressure guage reads quite low (nearly back to 0 on idle, and only just above 2 for normal driving), is this likely to be an oil press sender issue? It runs fine, plenty of oil etc...

Also another quick question, I occasionally get a small hesitation when I roll off and back on the throttle, as in, I back off slightly, and then when I squeeze the pedal back on it gives a small miss, and then pulls away fine, not the end of the world, but it never used to do it.

Any help would be great!

Cheers.

Oil pressure Sender units are notorious for giving up the ghost, have someone check your oil pressure with a mechanical gauge. Flat spots are generally caused by a lean mixture, you may have an air leak into the inlet manifold.

I notice the exact same thing with mine, could it be normal for a R32 GTS-T. My oil pressure does however rise to 4 after it has fully warmed up though.

My motors healthy (compression tested etc..) but the oil pressure gauge always reads low.

On start up when cold it will be just under '4' on the stock oil pressure gauge, and it only gets lower as it gets warmer.

When cruising at a consistant speed its quiet low, but at about 100km/3XXXrpm its in between '2' & '4'..

I don't really worry about it to much as I have been told the stock oil pressure gauge is useless, so I won't be able to get an accurate reading till I get a decent after-market oil pressure gauge.

i also notice the guage gets lazy around oil change time(5000kms)

Yeah mine went heaps low after I serviced it.

Was slightly worried with it being so low..

Hi again all,

Well I have fixed the problem, turned out to be an interesting one!

I had just replaced oil and filter before I started having this problem, and I used penzoil 10w30, which was a mineral oil, and as I read some of the posts is not the stuff to use, so I went to supercheap and got some fuchs 10w30 synthetic and chucked that in just to be safe.

Took her for a drive, and to my surprise, oil pressure is now back to normal readings on the guage! Not sure how that works being the same viscosity of oil and all, but thats how it hapened!

Cheers,

Rosco.

      I used the radium thing, makes the whole parallel assembly a lot more compact compared to any other way of doing it

      Racetronix also sells those ethanol content sensor bypass blocks. Adapter, Flex-Fuel E85 Sensor High-Flow Bypass, In-line No Sensor (ADF-FLEX-NS): Adapters - Flex Fuel | Racetronix Ethanol content sensor are originally designed to be on the feed line. These bypass blocks are meant to be ran in the feed line and not return. The continental ethanol content sensors have a 3/8" ID and not 5/16". This is why they are ran on the return line directly in conjunction with a low threshold sampling value VS in the feed with one of these blocks.    Haha we think alike, I used both original feed/return for 8AN feed, and one of the Hicas lines as a 6AN return. I also capped off and left the other Hicas line as a spare.

      R32 gtst speedo out by 10kph

      By -Jimmy- · Posted

      Interesting, I haven't read about the issue with oil getting into the speedo in the cluster before. I'll have to take more notice with mine. The speedo on my R32's when I've run factory diff and tyre size have never been accurate as far as I can remember. The non Type-M GTS-t did come with 15" 5 stud wheels and smaller brakes, but that's less than 5% of them.

      Good to hear the condenser you picked up off my brother worked all good. Do you think there could be an issue with your AC compressor itself or the clutch on it then? I don't know a lot about them so I can't really help but keen to hear what it ends up being. Keep the build thread going man, it's nice to look back on over time.

      This is a story of my life things, I learned eventually (thanks to someone calling me out) that my enthusiasm for discussing and sharing ideas that it came across as arrogance and I'm like... WTF?!    One thing I'm pretty sure I justifiably pride myself on is knowing that everyone will have things they can teach you, and you're always going to find out that something you think you know turns out wrong - you just don't know what it is until you get there.   Just the bursting enthusiasm that comes with ADHD when you hit something that gives you dopamine dumps can come across like you think everyone else is wrong or don't matter. But yeah, I'm a software engineer by trade and also do tuning in weekends and 100% have long had a reputation for  quickly making connections when resolving problems or forming solutions that I've sometimes had to take people form a long walk from start to end to explain how I ended up where I did when it's seemed "too simple" when I've stated my initial case, and had the "WTF" type reaction when they've realised how much was actually considered haha.   My reward is that I get all the curly problems thrown at me.
