RB20DET oil pressure gauge

Ok, here's the deal

Im trying to figure out if my oil pressure gauge is stuffed, or something is causing low oil pressure.

Sorta happens sometimes, it will just read 0 oil pressure, but the warning light won't come on

and then other times, it'll be perfectly normal.

It's started to do this more often, and doesn't seem to happen sometimes regardless of engine being warm/cold etc.

Would installing an aftermarket oil pressure gauge use a seperate pressure sender? or will it just hook onto the stock one? I just figure this will let me get an accurate reading, coz it could just be the gauge is stuffed.

They do have a reputation for playing up. Mine did the same, so I went and bought an Autometer guage for peace of mind.... Apparently fitting a new sender often fixes the problem.

Take it to a mechanic who has an oil pressure guage, get him/her to test it for you.

Or you can invest the $150 for an electric oil pressure guage, you will get a new sender that matches the guage. My Autometer has never let me down yet.

i seem to have the exact same problem mate... , normally at traffic lights during idling it will go to near zero, or else it will either stay ar quarter to 4 or 4, never went up above 4. i asked my mechanic and he says he might be faulty or the engine is seriously low in pressure!, well i'm getting a gauge soon to see if its faulty or not.. i heard that if its low in pressure, knocking will occur. But then again, when u start the car, the first few seconds the rpm will stay at 2k... if knocking occurs, it will go up higher at a fraction, if all is normal, the ecu will sense it and it will idle below 1k.. mine idles below 1k after a while.. so i'm assuming everything is alright !
