Crazy Oil Pressure

so i did an oil change a few weeks ago - car has been running as normal - no problems..

then noticed today my oil pressure dropped to 0 (greddy oil pres. gauge) whilst the stock gauge still showed between 2-3... pulled over just to be sure it there wasnt oil spilling out - no leaks - disconnected the sensor/plug for the gauge - plugged it back in - turned the car on - still showing no pressure - stock gauge still shows normal pressure 2-3 - drove it down the road - felt normal - tried a little boost - 7psi no problems - 10psi no problems..

Got home - let it sit for a bit - just went down turned it on - still showing no pressure on the greddy gauge but still shows pressure on the stock gauge - unplugged the sensor / wiring - clipped it back in - now its showing maximum pressure on the greddy gauge 10kg/cm2 but still normal on the stock gauge.. No leaks, drives fine but now i can hear a slight hissing noise / leaking noise above the injectors / below the TB about midway down the engine on the drivers side. Never heard this before. I got a bit of cloth and covered the underside of the throttle body to see if it was leaking - wasnt that, the gasket was replaced a few thousand km ago so it shouldnt be that.

... Would this be more of an electrical / sensor problem? Or further problems given the hissing noise?

The only other work i did was a fuel filter but i hardly think that would effect oil pressure. The filter isnt leaking - direct replacement for what i had in there. Not sure if that has caused the hissing noise

as if you even continued to drive it with no oil pressure on the gauge...

but yeh if its in you oil cooler if you have one you could have a blockage?

      7 Speed Auto transmission fluid change (Skyline, Q50, Q60, Fuga, Q70, A62 Titan and probably heaps of others including Navara...)

      I thought I'd do a write up on an auto transmission fluid change for a the nissan 7 speed Automatic. At some stage the genius engineers decided that the fluid in the trans was "for the life of the transmission", (which seems kind of self supporting to me) and removed the dip stick and fill tube (funnily enough there is still a casting for it). Anyway, for this job you do need 2 specialist tools in addition to regular hand tools, jack and good chassis stands. You need a way to pump fluid up to the transmission; I got one of these but there are plenty of other options: https://www.ebay.com.au/itm/364584087070 Don't trust the generic listing though, it does not come with the required adapter for the Nissan 7 Speed. You need one of these, can't do the job without it: https://navarapart.com.au/product/genuine-nissan-patrol-y62-d23-np300-navara-re7-dipstick-fill-connector1 You need a heap of compatible transmission oil. Could be Nissan, could be anything else rated for Nissan Matic S. You need at least 10 litres, I had 15 to give it a better flush... Also, you need some biiig oil catch trays, at least one of these, or bigger if possible (volume was fine, size was very marginal): https://autobarn.com.au/ab/Autobarn-Category/Tools-%26-Garage/Specialty-Tools/Oil-Service/Garage-Tough-Oil-Drain-Pan-Black-16L---GT1068/p/TO03191 Finally, a measuring jug is very useful if your pump does not have volumes marked on it, I got a 6l one: https://www.repco.com.au/oils-fluids/fluid-accessories/measuring-jugs/penrite-measuring-jug-6l-pmj006/p/A5322648 Oh, and gloves.....this stuff is horrible (not as bad as diff oil, but getting there) ....First, jack up your car.....

      So I mentioned the apprentice, @LachyK helped take the bonnet off. We just undid the nuts on the hinges and unclipped the gas struts, then pulled the bonnet back a little as the front was catching on the front bar.  I had a good look at everything today and have removed the rams, repaired/reset the hinges and bolted it back together like it never happened. I'll do a separate write up on the repair, and I also removed the poppers from the Fuga today too to save grief down the road.....as said above it is at least $5k to repair retail. I'm also happier about my ability to prepare a race car, and less happy about Nis-nault's engineering (I can hear @GTSBoy sAfrican Americaning) because the top hose of the radiator didn't slip off.......it snapped clean off. By practice I put the hose clamp hard up against the flare on a neck to make it least likely to ever move (thanks @Neil!). I guess that puts a little more pressure on the end of the pipe as it is further away from the rad, but still, that is pretty shit. I've put it back on for now as there was a fair bit of neck still there, but obviously there is no lip on the neck any more so I don't think I'll track it again until I have a new rad. Speaking of which....more research required. It looks like Koyo makes a standard size radiator in ally which I'll grab in the meantime, but I really want something thicker so might have to go custom in the medium term (ouch) Coolant still needs a refill and I have the pressure tester on it over night, but other than a wash down of the engine bay it seems alright. And @MBS206 noted something noisy on the front of the engine and I think I agree....time for a new accessory belt and tensioners I think.

      our good friends at nismo make a diff for it, I have one (and a spare housing to put the centre in) on the way. https://www.nismo.co.jp/products/web_catalogue/lsd/mechanical_lsd_v37.html AMS also make a helical one, but I prefer mechanical for track use in 2wd (I do run a quaife in the front, but not rear of the R32)
