No Oil Pressure At Idle..

[MrMike]

Hi guys just need to know if this is normal.......my car when its cold the oil pressure goes nearly to 8 bar and while driving settles down to about 4. sometimes at idle the guage reads pretty much no oil pressure......is this normal or is it time to swap engines.......?

Cheers

pump could be on its way out.

Does the gauge consistently read like that everytime you drive or does it fluctuate or jump around. Sometimes a faulty sender unit can cause that misconception...however i havent really seen one yet, only heard.

I would say its a faulty gauge/sender, mine does the same thing, 8bar oil pressure when cold, 2-4bar depending on revs when warm, on idle normally around 2bar but will sometimes drop right down to 0 and stay there for a while, sometimes if you let it idle while the oil pressure gauge is just above 0 it will all of a sudden jump back up to around 2bar and start working fine, some days it is perfect, some days it is fauly as hell, my old r32 gtst done the exact same thing! Very common problem.

If your concerned about it hook up a decent aftermarket oil pressure gauge and see what the readings are.

see told you i had heard it somewhere...probably in the million threads spoken of.

Im sure if your engine was actually seeing 0 oil pressure, your bottom end would be ticking away rather insanely.

i probably should have checked that.......bit embarassing really seeing as i am an auto electrician....lol

SAU is a much easier way of diagnosing my problems........

cheers guys.......

yeh faulty sender unit for the gauge, just get a new oil pressure gauge with the sender unit included, easy as.

[r32woohoo]

The gauge in my 32 is all over the place, as long as that warning light doesnt come on then you can relax

My gauge will read close to zero while my aftermarket gauge reads a steady 1bar at idle when warm
