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

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
