Oil Pressure


Recommended Posts

I'm not sure if this has been asked before but I didn't get what i needed to know when i used the search..

my oil pressure goes to about 7kg when cold.. and when its warm it drops to about 4.. i know that is normal as it has always been like that..

now.. after i had an oil change .. motul 8100... while driving the oil would drop to 2.. and when i rev it goes to about 3 or 3.5 but on constant speed is 2 .. (usually 4) and at idle its about 1.5.

but when i turn off the engine and start it again... it goes back to normal.. as in .. idle at 2 , constant speed at 4.. n revving makes it goes to about 5-6..

what is wrong with it?? is it just the oil playing up or theres more to it?

i understand ... more load means more pressure ...

but mine sometimes idle at 1kg and at constant speed is around 2kg.. that is abit low... since I've driven this car for almost 3years now and it was never like this before. and when i turn off the engine .. and start again.. it goes back to idling at 3kg instantly.. and while driving at constant speed is about 4kg ..

Hey all, my R33, 96MDL does the same thing, when driving around town its like 3-4 and when idleing its newere between 2-1.5. I used cheaper oils before and have now gone to Mobil1 10-30.. Maybe try changing oil back to 15-50, Maybe its common in sum skylines, either dodge gauge or lazy oil pump, Plz let me know how you go as mine is the same. Cheers

there is some very good forums on here regarding what oil to use..everyone should read them.

as far as using 0-40 vis for 25det...i wouldn't

    • Meh. I "see" a typo above, that should have been "sell".
    • The clutch pedal has a procedure for adjustment. This can only be done after you are 100% sure the system is absolutely free of air bubbles. You must bleed the clutch master cylinder first, then the "separation pipe" which is the clutch damper line, then the operating cylinder as detailed in the service manual. Also, you must fully depress the clutch pedal between shifts. Just because you can't feel it grabbing does not mean the input shaft is truly decoupled from the crank. At high RPM clutch plates are vibrating and moving around, you need to give it the best possible chance of success. On the BCNR33 Nissan revises these adjustment procedures slightly but not by much: I would be careful with trying to play games with these adjustments. As for the Nismo operating cylinder they say a lot of things. In practice the twin plate clutch needs less movement on the clutch fork to disengage because the whole stackup of the flywheel + friction plates + pressure plate is much taller. Personally if you find that the clutch still disengages too high at the top of the travel I would try the Nismo operating cylinder. Make sure to follow the air bleed procedures. 
    • Thank you for the links. I’m going to go with the 6pin plug you used. next step is rust treating re painting dash support bar and steering column then the 6pin cradle plug when it arrives in the mail.
    • I don't how much the car makes a difference or whether it is just a question of gearbox and clutch. On mine it's fine. Pull type Nismo coppermix twin (standard, not competition) on the 5 speed in my Stagea. OEM slave cylinder. Bite point is a few cm off the very bottom of the pedal. Clutch pedal all the way down to put in gear, and when heading off at the lights, there's a tiny bit of nothing and then it starts biting. And fully engaged before the pedal is all the way released. There's a bit of play at the top where the pedal does nothing anymore. Are you in Australia @ck_chino? If you are set on using a Nismo slave cylinder I have one new-in-box at home. Ordered it together with the clutch but didn't get it fitted. We can work something out if you want it
    • I am using a pull nismo coppermix twin in an r34 getrag box, had both the standard slave and  then the nismo one. Adjusted pedal to get bite point how I wanted , it is on the higher side, but would fully disengage past half way down.  I also read that the nismo slave won't work but I had no issues with the stroke, might become one later as clutch wears but 2+ years of happy motoring so far.  Take the above as one input only, specially as my setup is a bit unique in that I am using an S15 clutch master , cefiro clutch pedal, custom braided clutch line. Lots of variables at play.
