I just took my car for a bit of a thrash and when i got home i noticed the oil pressure light was on, but the oil level was fine and the engine didnt have any bad noises or anything. I was thinking that the gauge might be stuffed because it was the factory one, or maybe the oil pump is stuffed and i turned the car off in time but yeah i dunno. I dont really trust the factory guage but yeah has anyone had this problem?

Cheers

The pressure light is a more reliable indicator than the stock gauge (pressure reading). In your case I'd recommend not driving the car and keep engine running to a minimum until you can connect up a reliable (known working) mechanical pressure gauge to check the actual oil pressure (or none........).

Thanks for the replies. Im not sure how long the light was on, i dont think it was on for long at all otherwise i would have noticed it. Im just wondering is the main reason for no oil pressure be the oil pump failing? Because i can just buy another one and put that in? Or is there some other reasons i should also look at. Because the engine sounded fine no death rattles or anything. Im going to wait til its cold then start it and see if there is pressure. Thanks

for your sake i hope its just sender problem but it is common thing for the oil pump to fail on that model. Mine was probably only on for 15 seconds before i noticed and found it did alot of damage after i pulled it down. But i was up it when it hapened.

Yeah i was sitting in the garage and noticed it. But i was lookin at the dial not long before that and didnt notice anything. The engine sounded fine, but i shut it off straight away. I am hoping it is a sender problem, but yeah. Kinda a bummer i guess.

Arent the pressure light and sender switch different?

In which case, the light being on is bad, very bad.

My gauge reads 0, but my oil pressure light isnt on. When you are talking about the oil pressure light, is it the little light just below the oil pressure gauge?

I got a similar problem as well. When I am driving the car, the oil pressure does up and down quite a bit. When I am driving the car hard, the oil pressure closes to the max sometimes. But when I stopped the car in front of traffic light for 30seconds or less, the oil pressure dropped from the middle to nearly zero and it happened quite a few times. However the oil pressure night never comes on.

Any idea?

The factory gauges are a known early fail item (i guess some 32 GT-Rs are almost 20 now though :) )

Like others have said, test it with a good mech gauge somewhere. If the oil pump is stuffed, your engine most definately would sound like it too by now.

0 oil pressure on the gauge without the oil pressure light turning on means its the sender.

oil pressure light on is bad news.

hey,

My stock oil press gauge is at zero and the light is on, but on my greddy oil press gauge the pressure is showing a healty 46psi...should i be worried?

what the person who installed your gauges may have done is remove your standard oil pressure switch and replace it with the aftermarket one (i.e. they didnt use a sandwich plate). therefore the reading of no oil pressure.

have a closer look to see if thats what they have done.

if not, i'd be getting it checked with a mechanical gauge (mechanic screws a mechanical gauge into where the standard oil pressure switch goes).

Can anyone tell me exactly where the oil pressure is taken from, or the oil sender or what it looks like etc?

My new car the gauge is all over the place but like mentioned above if its sitting idle for a minute or so the gauge will drop to zero but the light is not on.

if the lights on but gauge is still reading nominal pressure, give the sender a tap with something solid, should cause the sender to recalibrate itself. This happened to my engine after rebuild...i was like...fu€k... they've forgot to do something, gave the sender a few slight knocks and it came good and hasn't played up since, over 12 months ago now

      S15 Spec R

      A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always!

      R33 Fuel Pump & Brakes after alarm swap

      Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
