Rb30 Oil Pressure Shows 0

[teng]

Ok. On my KCR31 Dash top right hand corner there is an oil press gauge (i think). It shows 0, 60, 120.

Now it only shows 0 no matter when the car is cold or at whatever speed.

Revving doesn't show anything either.

Is the gauge meter or the oil pressure sensor dead and where is the sensor located on a RB30?

Thanks.

is the oil light on? probably a dead gauge.

the sensor is on the drivers side of the block

Errrr. Some of my lights on the dash are blown so i don't know if the oil light is on but it drives fine with no problems.

Is the sensor the same as that of a ECR33 RB25DET?

Get a mechanical oil pressure guage and plum it up where your normal oil pressure switch would go. If that reads appropriate pressure it should be fine.

Its more than likely just the sender though. its just behind your oil filter

ok. I'll check it when i get to work. Not enough garage, had to park the car at the office.

Thanks for all the information.

Ok solved it, The hose from the sender has cracked due to age. Replace a new one and it's all good. The gauge still reads 0 at idle but when the accelerator is pressed, it goes up.

[ClutchBurndout-:(]

0 at idle? bit low for idle isnt it?

at idle mine shows 1.4 kg, which is just under 20psi??!?!

Maybe the sensor is not working properly. Either that or it's the gauge. But my engine is RB30S so it's a bit different i think. The sensor is located at the engine bay passanger side. I do have a spare sensor so maybe i'll chuck it in tomorrow and see.

The picture is before i fixed the hose at the bottom.

You would find that the sender is not set to work with that dash and that is why the pressure will go up with rpms but 0 at idle.

also the stock gauges are notoriously inaccurate

[teng]

Ok time to finalize things here. Got a spare gauge, installed it and..............it's the same. lol

Just got an stock oil pressure sender today, installed it and it works. Sender is next to oil filter.

It doesn't drop to 0 anymore when engine is in idle.

Problem solved. Damn oil pressure sender.

if the light hasnt come on its a good thing. if the light comes on then you might have a slight problem. lol. get an aftermarket one.

But by personal experience...if it aint broke, dont fix it.
