no oil pressure

[sanches]

i have no more oil pressure since this morning, and yes there is oil in the engine. the oil light stays on and the gauge stays at 0psi.

anny one had the same problem or have an idea what it could be?

the car only has 42.000km

[Trev-the-Rev]

Is the engine making any unusual noises? I would strongly suggest you don't drive it until you've had it checked out by the dealer.

[Ekona]

Are you sure you've got oil? The dipstick is about as much use as a chocolate teapot at times, and given that both the oil sender light AND the pressure gauge are telling you the same thing (are they read off the same sensor though?), I'd be triple checking the oil level.

It sounds like you have he symptoms in post 10 below

This could be a faulty sender or something more sinister like a failing oil pump - you absolutely should not **** about with this, you could total your engine. Get it to a dealer, better safe than sorry they will run the necessary tests

i'm devenetly not driving it untill its sorted out. no strange noises at all.

the oil level was in the middle of the marks on the dipstick.

faling oil pump?? on a car with 42.000km? that would be verry weak

Good luck - you're doing the right thing; unlike the guy in that post, what was he thinking leaving it idling to see if it got back to normal region

What on earth was this guy thinking about?

[sanches]

a added some oil and there still was no pressure, started the car again 2sec later and there was pressure and when i wanted to drive again a few hours later, no pressure, try'd again 2 sec later and pressure again

i looked in the hole where you ad oil with a flash light and i can see the oil flowing really good but i only had the chance to check it when the oil light on the dash was out.

i'm going to the nissan dealership tomorrow to get it read out by the computer, i think it will be an electrical error.

what do you guys think?

[Chesterfield]

Get it to a dealers. Starting and stopping when there is a pottential oil flow problem could result in you needing a new engine - as dorian (prescience) posted above - do not risk knackering your engine.

 

Dealer visit and new oil pump, worst case scenario a hundred quid (or Euros) or maybe more given dealer pricing.

 

Keep trying to find/fix your problem yourself and the worst case scenario is that you need a new engine costing a few thousand.

 

Your choice.

Oil pump failure, dicky sender unit or blockage, get it tested asap, an engine wont run long without oil, it will fail and seize .... dont run it

 

you're not safe because you have oil in the engine, if that oil is just sitting in the sump

[Adam@Z1auto.com]

sounds like the sending unit...quite a common issue

it is the most likely Adam but just incase i wouldnt use it

[sanches]

isn't there a 350z workshop manuel i can download or something so i can locate al the components etc.

[Adam@Z1auto.com]

absolutely, would definitely get a tech to look it over - hopefully nothing serious

[sanches]

problem solved... by just changing the oil filter and oil.

and thanks for the manual, thats gonna be verry helpful in the future

[Trev-the-Rev]

Great news mate. Was this carried out by the dealer?

[GIXXERUK]

hmm very odd, was the oil like sludge ?

[sanches]

no body touches my cars but me mate

the oil looked like it was in to long but not like sludge

[Trev-the-Rev]

This is strange because I never known of dirty oil to cause massive pressure fluctuations such as you were experiencing.

[sanches]

me neither, but i'm verry glad it's solved that easely

[Trev-the-Rev]

I think I would feel the exactly the same. Good result anyway

[sunset350z]

When i bought my car the oil pressure was really low, it didn't go over a quarter. Once i changed the oil, the pressure went back to normal which was a great relief. This shows that the performance of oil degrades over time and use.

Yes that is very true - but there is a world of difference between 15psi (which I experienced myself) and zero. I wish the guy well, but he's a mug if he thinks an oil and filter change have really solved it. You can only take horses to the well etc...
