Not sure if anything is wrong? but wen i start my z the oil pressure is high. so i just cruz till she is warm then she goes to the norm (i dose let it warm up aswell) allthough sometime not allways it will drop after a while to allmost 0, give it sum n she moves up 2 1, sometimes it dosent even move. turn it off strat up 10 min all is good no problems? i thort it could be the oil im using? 5w50 i think and how cold it can get in camden? pleasde help i want to prevent ne thing else going wrong> :|
maybe your oil pressure unit is on its way o ut. Mine did exactly the same thing then just stopped working totally. This happened about 6months ago and i still havn't had time to fix it
Same problem It could be the pressure relief valve or as you say the pressure sensor. As the oil warning light never comes on, the best bet is the sensor.
5w50 too thin the service manual puts the lower limit for oil at about 10w40 for our conditions. maybe look into replacing
oil gauges on the Z's dont work properly I'm haveing the same truobel with mine and few I have talk to are haveing same prob. But your oil is to thin take MR trickle advice and change oil.:YD
I agree, having probs myself. Not really problems but, I've just had my oil pressure switch/sensor replace and am using 5W50 Mobil 1 Super Synth, I'm finding the same thing is happening, and with out an owners manual to tell me what oil to use I find that next oil change in goes some thicker stuff.
service manual here If you ever need a quick look up to check some stuff out it can be found <A HREF=http://300zx.co.uk/cgi-bin/manual.cgi>here</A>, the online version of the service manual. Many people on here have it on CD, me included.
yeah I know about the online one....but. Ya can't use it if you're in the garage working on your car unless you have a laptop hey?!....
good idea Stillen.....but it's flawed have you seen how big the damn service manual is?!!!! I mean seriously with the good ol bubble jet plotting away at the speed of a damn dot-matrix I would've been through 50 cars by the time it's finished printing the whole thing!! Plus if I were to do it at work, try and explain how come a new cartridge was used in 2 days??
For the nissan unit...... at warm idle, the gauge should read 2. While driving, it should read 4. When started cold, it should read 6 and eventually move down to 2.
