V8SkylineMAN --> Yep only drops ones and the sorts itself out or stalls, this happens eveytime I slow down, and change gears down. If I dont keep the revs up it will go to 0 then back to one. But yer it sorts itself out after going to 0, but its a pain and the power steering gets heavey as its about to turn off but then comes good.

Definately not your idle circuit then....I would also think that it is your bov's......try taking them apart and giving them a bit of WD-40 or summing....the plungers MAY be slow to respond? due to lack of lube.....but also put your stockers back on...or buy some more stockers

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

I also have a 32 gtr, an have the same problem... or should i say had the same problem until my my engine died !!!! :)

It could be the guage... iv also heard that the oil pump bolts can come loose

If i had my time again i wouldn't of put it down to the gauge just in case, an put a full mechanical gauge on it !!!

As iv just found out that gtr engines are F*#ken dear to rebuild !!!!!! :)

Like everyone else i've experienced this myself recently. R33 gts-t.

Changed my oil a week ago, same stuff Motul 4100 but i overfilled it a bit and i changed oil filter from a cheap brand to a ryco one. I've used same oil before and i never had a problem.

Only started happening after my last oil change.

It wouldn't have anything to do with the oil being overfilled? (i don't think so)

Mite be the ryco filter..but its a good brand so once again i doubt that would be the culprit.

It also only happens after i've been pushing it for a while. Gauge drops to almost 0. Pain in the ass! and scary.

Go figure. :)

your idle is playing up because there is a leak in your vacum line that goes to the top of your bovs.

If the bovs were stuffed and the piston inside didn't seal you would have the equivilant of a leak. If they are new its not the bovs, more likely one of the vacum hose's (as there are two one from each turbo and for each bov) has a small hole in it, or is not connected properly.

The oil issue is an problem (mostly likely) with the guage, all the nissan electrical ones play up at some point, mine is playing up atm as well. Get a cheep mechanical one installed under the bonnet so you can see if you have pressure when the other fails.

The oil "light" is separate form the guage and if it is on.... you have no oil pressue (pump) or no oil, STOP your car, check oil and walk. It is very rare to have the light fail by comming on. and its bad if its on. :headspin:

come on, In what way does the water system (radiator etc) effect the oil pressure? thats just silly.

and you do realise that the "engine" oil light/guage is not connected to the power steering oil? as its a completly seperate system and is completly different oil, not even the same colour.

but keep checking it, and you might want to watch the steering oil level as your wheel might :flamed: stop spinning

My 1992 r32 GTR did exactly the same thing one night.

The oil px guage was really low and ended up going to zero. It would only rise if i revved it. Weird thing is it came good next day. Checked wiring to oil px sender(gave it a wiggle). Only thing I can explain is a bit of crap got stuck in the orifice of the oil px sender. It cleared itself out I guess. Due for an oil change soon anyway(every 5000k).

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Maf is a question mark but TPS  I have set at 0.47, the fact that I’m getting proper voltage range out of it with the key on leads me to believe it’s functioning properly. I’m getting proper voltages on basically everything. I still need to look up voltage ranges for z32 maf and test that

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Honestly no not at all, but it’s a very basic tune, it’s stock injectors q45 tps and z32 maf. Other than that it’s a completely stock base map. The file is from nistune and from my understanding if it was tune related I would be able to unplug maf and tps and it would still start even if it was a really shitty start. I have tried starting it with coolant temp, maf, and tps unplugged none of those 3 togethor or individually changes anything

      What does it look like with highway driving? And yes, I had a similar thought as Duncan. It looks quite similar in my Stagea and I have made myself accept it as normal. Might have to look into it some day   Highway gets as low as 10l/100km on my end so I'm not as worried about it being a mechanical issue. More likely just the tune on the haltech.

      RH9 R32 GTR Build Thread

      By OST Micah · Posted

      While I was waiting for the new parts to come in for the charge pipe and radiator I decided to do some turbo modification. The drive pressure (exhaust backpressure) was a lot higher that I thought it should be. For 32lbs of boost drive was 55lbs. The turbine housing is a 1.10AR and my turbo builder has suggested to go to a 1.25AR. To test if a larger AR would do anything to reduce drive pressure AND not spend any money I decided to hog out the divider in my current housing. I removed it from the inlet and the whole way through the housing.  After reassembly and testing it doesn't look like this modification did anything for reducing drive pressure or requiring more fuel (making more power). Oh well, it was worth a shot. We'll get some data at the track if it makes it past the 60ft. I also machined a $7 shift knob off Amazon to fit my Stillway shifter since I didn't like the Stillway shift knob. Next on the list was the radiator replacement and fabrication of a new intercooler tube that had no silicon coupler. No pictures of this - I was short on time each night after work to get this done and didn't stop to take pictures.  Next was to get the clutch disks out and replaced. Previously when installing the dogbox I had ordered a set of the same sintered iron disks I had been running because I switched to the 26-spline input shaft. I thought it was odd that they didn't have any markings or brand name on them like all my old disks had but installed them anyway. At the track I could not get the clutch to lock up using my normal strategies. After two track nights I reached out to the clutch manufacturer and ask their thoughts. They said they had to switch the material out because they were having trouble getting the original material and that this new material would not take to being slipped very well.  So out with the first set of 26-spline disks and in with the correct material 26-spline disks. While I had the trans out I added an inspection/service hole. I've wanted one of these for a while. Now I can have a look at things and change the front cover shimming when needed (clutch wear). I hustled and got the clutch change done in a few hours on a Saturday. Hopped in the car and drove home. On the way home I did a 1-3 pull. When shifting from 2nd to 3rd the core plug in the back of the cylinder head popped out and dumped all the coolant. Thankfully I was only 30 seconds from home and coasted it there. Datalog showed nothing unusual and 2.5psi of coolant pressure. That plug has been in there since 1992 but I guess it worked its way out. Pulled the trans AGAIN and replaced the plug, JB welded it in, and made a brace. Also deleted the head drain I had added in during the bearing issue fiasco.  I am currently changing my boost control plumbing to make it cleaner. After that is done I'll make another attempt at getting past the 60.
