i'm not sure for the idle oil presure, didnt you realise that after u've boost the car in high rpm for a while, the oil presure will goes to almost 0, when normal cruising is like 4 or 3.5.. anyone got idea bout it?

at operating temp. ie 80 degrees oil temp it should be on about 2 on the gauge when the engine is at idle (ie half way between 0 and 4). stock gauge is not very accurate though, so if oil pressure is a concern, buy an aftermarket gauge. when cold it will be more like 6 at idle.

I hear the oil sender unit can be unreliable

Try cleaning the wire contact on the oil sender unit if the readings vary.

Or try replacing oil pressure sender unit.

I find that on Start Up the Oil Pressure can shoot up to the Dash just below 8.

Highway crusing can be around below 4 and just normal suburb and city driving, it can be just above 0.

Ok, if you want to do it properly the procedure is as attached.

Things to know:

The sender unit for the gauge is notoriously unreliable. A low reading is commonly attributed to a fkd sender. They aren't overly expensive, nor hard to fit.

The oil pressure you have is dependent on the viscosity of oil in the engine which in turn is dependent on the oil temperature. For some reason people equate oil pressure to wang size or something. A higher reading is not necessarilly better.

The guage measures pressure in kg/cm2.

      GReddy Injector Help!

      By GTSBoy · Posted

      Unless there's something particular about the Greddy manifold's injector holes that I'm not aware of, those injetcors look to be totally wrong. They would absolutely want to be spaced up to get those long snouts out of the runner. Which, I think, is not usually the way that that problem is solved. I think the problem is solved by using the correct injectors, which would be much more like what Andrew posted.

      GReddy Injector Help!

      Thanks for the reply, So i've continued playing around, and fitted the injector adaptors onto the injector, the fuel rail is not able to be mounted now as the injectors sit a bit further out. I suppose the point of the adaptors is so that the injector nozzle isn't so deep into the intake? I suppose 1mm extra on the o-ring would do it but still can't mount the rail onto the intake haha. Waiting on a reply from Aeroflow I'm sure there's something stupid that I'm missing...

      GReddy Injector Help!

      I have a radium fuel rail on my Greddy manifold and used the supplied radium fuel injector to manifold adapters (The round green things pictured). I did always wonder if you could just go ahead and use the second lower hole like you're doing... Wouldn't thicker o-rings solve your issue?

      From what I've seen and experienced first hand with those powder extinguishers, they're good to use to break a window and escape the car, and half the time then do f**k all to stop a fire. You just need much more than 1KG worth of powder. Not to mention, half the time it's an engine bay fire, and you can't easily, and do not want to completely open the bonnet, so you're left pretending to be an American Infantry... Spray and Pray baby!   And then 100% that shit is really destructive afterwards!   Realistically, those little ones at a race track might help you keep the fire from growing and give the fire marshal / truck a chance to actually get to you with their multiple large bottles.   For a road car, these days, prepare to deboard as quickly as humanly possible, and move to safety. Allow insurance to fix replace it (unless it's like a rare classic etc, then do nearly everything possible to save it!) Keep the little extinguisher with you to help protect other things around you from burning while you stand there singing "How can we sleep while our beds are burning?"   Secondly, powder extinguishers I freaking hate for indoor use, (this isn't really relevant to a car) as you will get a powder fog around you, and it can be disorientating.   When I did fire training when at BlueScope Steel, they have (had?) their own fire brigade on site. We did all the training, and at the end we were told, "If it's an indoor fire, and you need to use a powder extinguisher, we as the fire brigade would rather you just exit the building, you're more likely to get lost in the smoke and powder fog than do much help, so just GTFO" And pretty much that was what they said for most other fires too, grab extinguisher, if it's much more than paper in a bin fire, use extinguisher to get you and others out of the building to safety...   Part of me wishes when my Skyline caught alight many moons ago, I let insurance sort it out, instead of putting the fire out... part of me now says "But I've saved a classic before it was a classic!"
