Oil Presure Problems

Hey

I was driving my R32 GTR and I got held up in some trafic, I was idling at 1k and noticed my oil presure gauge sitting on 0. I thought to myself "FU*K", wtf is going on. When I slowly started to move it would slowly climb up, but the back to 0 when I came to a stop. When we started to move again and we got going, the gauge would sit normal, about 2. When I came to a stop again the gauge went to about 1 and stayed there this time. When I got home it was reading normal still, I got out of the car and looked under, I found no oil on the ground.

Can anyone tell me WTF this is or whats making this happen?

Thanks

did you have any trouble accellerating? revs were fluctuating and dropping at all?

i had a similar problem with my engine, turned out the radiator had ran dry of water (the cap was faulty), so check your radiator and fill her up if she's dry.

this might not be the case, but have a check anyhoo

Hey

Radiator is full

My revs are fine when driving but when I slow down they go to 0 and back to 1, sometimes it stalls, I asked my tunner and he said its something to do with my BOVs. But I havent asked my tunner about this as he is closed, so im trying to get my answer on SAU.

i would get mechanical oil pressure guage, and check it against that, they are only about 50 bux from supercrap or something....im not saying put a cheap ass guage in your gt-r im saying use it to see if yours is out, or your oil pump is sha99ed.....if at all possible have them hooked up at the same time to see any discrepancies(sp?) in readout.

Idle prob:

Have you had your throttle body off at all? ever?

Also could be ilde circuit faulty making revs jump around.

Or the speedo? :headspin:

I experience the same thing in my 32 GTS-t... it will sit REALLY low (not quite on 0) on the oil pressure guage, and then climb to slightly above 1/4 when driving around... i don't think i've ever see it go over 3/8th (between 1/4 and 1/2) on the guage... i'm hoping its just a faulty sender, not a shagged pump or something

Dont trust the reading of the stock oil pressure gauge.

I had a similiar prob when i had my idle issues with my sard 550cc injectors. Everytime the car would go into spastic idle and go back to normal idle the oil pressure gauge used to just go to 0 and sit there and sit there for ages till i turned the car off and on again, but the oil pressure was normal while the gauge said 0 pressure everytime.

The stock gauge is also said to be very slow reacting to a proper electronic oil pressue gauge.

Hey

I restarted the car later that night when it was just warm, and let it idle for 10-15min or so and the oil gauge sat on 2. When it was on 0 it would slowly climb when i reved it and moved a bit but then it droped back to 0, after the traffic cleared and I got going it was ok, when I came to a stop again it sat on 1 and didnt go to 0 again.

I didnt hear and werid sounds from the engine or anything.

My Revs are a diff matter I think, car idles at 1k and drives normal etc, when I slow down tho the revs dont stop at 1k again it goes all the way to 0 batt light flashers and then it comes back up to 1k again, somethimes it stalls. I am told this matter is something to do with the BOVs. Never use to happen and I was running 2 hks bovs and the stock pair (4 BOVs, Stocks sealed) I removed the stock ones as I was told it was for the best and now the revs do that. Pain in the ass it is, but thats not my may concern atm, the oil presure is and im pritty sure its the sender.

Thanks

Got the same prob too in a 32 GTST. Oil pressure drops to zero (and the red low pressure light comes on) when I come to a stop, then picks up when I start moving again. Occasionally stalled too.

But I had a few oil leaks in the steering rack, sump, etc. Mechanic fixed that up the other day and hopefully that should fix it up.

Who ever told you to remove the stock gtr bov's is an idiot. Put the stock gtr bov's back on as they have been used on gtr's and supras with over 500kw@wheels withput any problems.

      Steps to DIY sanding car back ready for respray....

      By Murray_Calavera · Posted

      Yep, if you are applying filler it sounds like there is something wrong with the body lol. Safe to assume there is going to be a lot of sanding going on if your still applying fillers.  Picture a perfect bare metal panel, smooth as glass. You lay down your primer, it's perfect. (why are you going to sand it?) You lay down the colour and clear, it's perfect. No sanding at all took place and you've got a perfectly finished panel.  You won't be chasing your tail, sounds like you were prepping to start laying filler. If your happy with the body after the sanding, there is some bare metal exposed and some areas with primer, no issues at all, start laying the filler. You are safe to lay filler on bare metal or primer (of course check your technical data sheet as usual for what your filler is happy to adhere to).  This isn't a 100% correct statement. There is primer that is happy to adhere to smooth bare metal. There are fillers that are happy to adhere to smooth bare metal. Just make sure you're using the right materials for the job.  Typically if you are using filler, you would go primer, colour and clear. I've never seen any instances before where someone has laid colour over body filler (maybe this happens, but I haven't seen it before). So your plan sounds pretty normal to me.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      I don't think there's any way someone is push starting this car.. I honestly can barely move it, and moving it and steering it is just flat out not possible. I'm sure it is, but needs a bigger man than me. I have a refurbished starter now. The starter man was quite clear and consise showing me how nothing inside a starter really should contribute to slow cranking, and turned out that for the most part... my starter was entirely fine. Still, some of the wear items were replaced and luckily it didn't show any signs of getting too hot, being unfit for use, etc. Which is 'good'. I also noticed the starter definitely sounded different, which is a bit odd considering nothing should have really changed there.... Removed and refit, and we'll pretend one of the manifold bolts didn't fully tighten up and is only "pretty" tight. GM only wants 18ft/lb anyway. I also found a way to properly get my analog wideband reading very slightly leaner than the serial wideband. There's Greg related reasons for this. The serial output is the absolute source of truth, but it is a total asshole to actually stay connected and needs a laptop. The analog input does not, and works with standalone datalogging. Previously the analog input read slightly richer, but if I am aiming at 12.7 I do not want one of the widebands to be saying 12.7 when the source of truth is 13.0. Now the source of truth will be 12.65 and the Analog Wideband will read 12.7. So when I tune to 12.7 it'll be ever so slightly safer. While messing with all of this and idling extensively I can confirm my car seems to restart better while hot now. I did add an old Skyline battery cable between the head and the body though, though now I really realise I should have chosen the frame. Maybe that's a future job. The internet would have you believe that this is caused by bad grounds. In finding out where my grounds actually were I found out the engine bay battery post actually goes to the engine, as well as a seperate one (from the post) to the body of the car. So now there's a third one making the Grounding Triangle which is now a thing. I also from extensive idling have this graph. Temperature (°C) Voltage (V) 85 1.59 80 1.74 75 1.94 70 2.1 65 2.33 60 2.56 55 2.78 50 2.98 45 3.23 40 3.51 35 3.75 30 4.00   Plotted it looks like this. Which is actually... pretty linear? I have not actually put the formula into HPTuners. I will have to re-engage brain and/or re-engage the people who wanted more data to magically do it for me. Tune should be good for the 30th!
