dc2R oil pressure

[szymonsta]

hey guys, ive noticed that my defi oil pressure gauge shows idle pressure of ~150kpa and max pressure ~600kpa, the needle seems to rise to just under 6 and then 'bounce' back a little. the gauge calibrates ok so i think it is accurate, but just wondering if u guys have the same experience? ..and why does it 'bounce' back? is there a cap on peak pressure? sorry for mechanical noobiness of this question

Oil pressure drops when VTEC initiates due to Oil-pressure operated switch opening. Also there is an oil pressure relief valve.

What you are saying seems normal from what i've read and in line with what others experience.

cam - i think VTEC engagement is not what syz is talkinga bout.

it could be the way the relief valve operates, i see mine hit 80ish then "settle" to about 77 in normal driving...

the valve is there to prevent oil pressure being too high...

[szymonsta]

i thought so. it seemed as if theres a valve of some sort which releives pressure beyond that point.

thanx guys!

This is correct
My defi sits :

idle: 2.0 or slightly above
under vtec: 6.0
vtec: 5.5

and it's electronic

I know that this is almost a year old thread but I have a relevant question

Would idling at 150kPa/21.8PSI be normal? I had worries as the pre-set low oil pressure warning on the defi was set at 150kPa and it would occasionally beep.. (I have obviously had this warning changed to 120kPa) I do realise that oil pressures will differ from car to car but having the car idling on a "standard" low oil pressure wasn't very pleasant...

What would a dangerous oil pressure level be?

[DLO01]

22psi seems lower than the norm, but probably ok at Idle

Whats the Max oil pressure your getting?

[arron]

Max Oil Press would be just a little under 600kPa/87PSI.. which seems normal and healthy...

Only the idling has got me a little worried.. It would only dip under 150kPa/22PSI when the engine has been running for at least 20 minutes and the oil temps are hovering around 95 degrees C.

[DLO01]

So your Idle is fine/normal, not low?

[arron]

I'm not too sure if idling at 150kPa/22PSI is normal.. I was asking you if you knew that was ok...?

Lol, thanks for your help so far though!

[tinkerbell]

20psi @ idle is fine

[DLO01]

Was refering to engine speed at idle. Is it normal or lower than norm?

Tink thinks its fine too.

[arron]

Ahhh my engine speed.. engine speed is all the same.. nothing has changed from the norm..

Sweet.. Thanks again fellas

[BlitZ]

20psi is fine for idle.. more important is you wot vtec or at 3krpm

[arron]

O rly?

What sorts of pressure figures should I be expecting at around 3000rpm and vtec high cam?
In the meantime, I'll go for a drive tomorrow and have a look!
