Oil pressure drop to zero!

Ok people, one thing has to be pointed out which will clear up most of the questions.

The light works independantly from the guage, however, they are both from the same sender.

If the guage drops to zero but the light doesn't come on, then the guage is your problem.

Oil pressure is vital to your engine, if the oil pressure drops to zero and you didn't switch your motor off 5 seconds ago, then the engine is cactus anyway.

I bent my crank and had a 55thou bend in my cradle and still got 4psi oil pressure even though every single one of my main bearings had shat themselves. Chances that you would have 0 oil pressure is virtually impossible unless you totally screw all mains, plus all big ends plus the relief valve in the pump.

Get an aftermarket guage with a seperate sender....it is vital that you know your oil pressure on a more fine scale than 2, 4, 6. With the autometer guage, I know when my pressure drops 2 psi.

$180...buy one...forget your problems.

You people are like a bunch of little kids. I mean...honestly, oil pressure drops to zero, instead of taking it to a mechanic or even phoning one.....you get onto the Forums and ask people for an answer that could take days to resolve. Then ask for the price of something you can easily get by going down to your local repco or autobarn store. C'mon, do you live locked in your basement or do you actually get out into the wild every now and then. Common sense often prevails in these situations and it seems as though many people are lacking it these days.

Yep, we're the little kids!!!

Just trying to help the guy!!

Anyways...I guess it was just an indication fault after all...as his engine didn't blow up 5 seconds ago??

Honestly..it's not a battle of wits here (I hope) ....

We're just people with something in common.

Skylines and being helpful??

If someone agrees that's great, if someone doesn't......that could be even better!

It's called looking at things from 'all' angles.

Anyways...have a great week guys.

Couldn't agree with that advice more 3LIT3, shouldn't be too lazy to grab yourself the right tools to make sure everything is ok :)

And, dear superspit

mmmm......I wonder if people are helping sometimes, or just accelerating the ageing process of humans. Read the forum threads so far?
Yes Morgs...and I reckon, going back through these posts, that I have already.

Thankyou, champ!!

Perhaps I should rephrase, have you got something specific to say to me about my contribution to this thread, PM me. I'll give you my mobile number and you can talk to me directly instead of behind the forum.

Hiding.....??? nup, never...don't need to!

Paranoid.....maybe one of us is?

Your mobile number, why would I need that? For advice? Give it to the worried bloke who started this thread.

Thanx anyway.

I never disagreed with you....infact I totally agree with your aproach...but it shits me when people ask stupid questions and don't do a little work for themselves and rely on people like you and me for answers.

Don't get your back up...I am only saying that he needs to pick up a phone for answers to questions like...how much for a guage.

Other than that....I totally agree with what you first said.

Sorry 3LIT3, it wasn't you who was the one wanting me to PM you and have a 'chat' rather than "hiding behind the forum"...what ever that means??

We're cool?

I do see your point, and appreciate that....well said. :)

haha, dun end up fighting mates~i know my questions are quite stupid to somebody know about car, but in fact i know nothing about car, and was just trying to find out whats the possible failure before i bring my car to garage and spend shit to repair, and after i read all comment s here and other forum, i got some idea it might just coz of the sensor problem or at worst the oil pump failure...my question might stupid, but i hate going to workshop and hear those mechanic saying what the things i have no idea. so better get a little knowledge before i go

FYI people, that red light on a GTR also comes on when the oil temp reaches a preset limit ~130 degrees...

Thats good to know, i didn't know that.. I've had my engine oil temp pretty high on the track tho and haven't seen it come on, i would of said it would of been pretty close to 130 deg (before i got my oil cooler)... where did you get this info? Is it the same on R33 GTR? i'd assume so.

Got it from my Aus R32 owner's manual. I don't see why it would be any different for the 33... will scan up the page when I get a chance if you want :)

I only discovered this when I had the light come on (and stay on until the car cooled) at the track last year and the oil pressure gauge was still up. Stressed I'd done a big end, but sounded fine after cooling.

I actually didn't go to the manual then, but after removing the 3 centre gauges and replacing with 3 defi gauges subsequently, the light stayed permanently on. From here I suspected that the oil temp would trigger the light too, so I checked the manual and that's what it said :)

sorry for the ramble

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler

      Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?

      Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
