So after running around on five cylinders and a boxer-like rumble for a few days, the verdict came back that an injector has died, which Nissan say is an $800 fix with a month's wait to get one shipped ex Japan.

Now, I suspect that &450 for an OEM injector is a bit silly, and I could probably get either mine or a secondhand part reconditioned for much less, or a full set of new ones for slightly more. A quick yellow paging has turned up B&M Fuel Systems in Richmond, does anyone know/recommend anywhere else?

I'd think that lots of people would have standard injectors hanging around for GTST's... since they upgrade them to bigger units, but less would for NA's....

Good luck mate, that quote from Nissan is stupid, ignore it and buy local / second hand.

You will likely get a brand new set of upgraded injectors for that price! Nissan know very little about performance cars :P

I hope you're implying he should also purchase the equipment required to support upgraded injectors too :thumbsup:

OP, I'm curious as to how it was diagnosed as a faulty injector? It's pretty unusual for an injector to go like that. Have you sussed out the ignition system first to make sure it's not a coilpack/loom/spark issue?

If it's the injector, you could probably take them all out and get them reconditioned / flow tested for $200 or so.

That's what I thought too, even supported by some quick searching under 'why does my skyline sound like a boxer?', but they tested all the plugs and coil packs and they were fine, compression tested the block and still nothing, then looked at the #6 injector as the source. Took them 5 hours to figure it out apparently.

Spoke to B&M this morning, if I were smart enough/had the tools to remove it myself, it would cost $40 to recondition the dead one, or $120 for a replacement.

2+ hours of labour, they aren't the easiest things to remove / install... There's $250...

Verdict's in - $120 for a reco'd piece, or $190 for a new one with a days wait on parts. Much better than $460 and a month ex Nissan, Odium, you're right - I'm looking at a few hundred in labour.

She'll most likely be going to the farm in 12-18 months so I'm just replacing the dead one and hoping for the best. Are in-fuel injector cleaners worth using?

Aznew charge $25 I think to clean and flow test an injector. Don't bother with in-tank injector cleaners, the mesh filter in the top of the injector is most likely blocked.

If you remove the injectors, make sure you replace the orings.

So i've finally got her back, and it's not what it seems.

Injector - Fine.
Coil Pack - Fine.

The culprit? The plug into the coil was corroded to hell, and had corroded the wire into the plug away completely. Real pain, and about $800 in labour to fix.

Which brings me to my next question. Given the fact that it was misdiagnosed by nissan service, and having them repair it wouldn't have fixed the problem, and the actual cause was something that (according to B&M) should really have been picked up on if a decent look was had into it before deciding it was an injector, and subsequently not testing the injector to confirm it, how likely would I be to recoup some of the costs from nissan service, given they have a three month warranty on their work?

Yep, given I was told it was an injector issue, I had it booked to replace. Didn't find out what it was until he'd pulled it all apart and tested the injector to find there was nothing wrong with it, so then he had to reassemble the whole show to troubleshoot it from scratch.

Half the cost is in removing and refitting the injector that was apparently busted. So the dealers wrong diagnosis cost me $500, when you include their bill.

I'll take it up with them, hopefully they'll be decent about it. Only sure thing is not asking guarantee's nothing.

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

      By Duncan · Posted

      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.....

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

      By Duncan · Posted

      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)

      R33 persistent issues. P/steering and lag/misfire

      By GTSBoy · Posted

      What are we supposed to be seeing in the photo of the steering angle sensor? The outer housing doesn't turn, right? All the action is on the inside. The real test here is whether or not your car has had the steering put back together by a butcher. When the steering is centred (and we're not caring about the wheel too much here, we're talking about the front wheels, parallel, facing front) then you should have an absolutely even number of turns from centre to left lock and centre to right lock. If there is any difference at all then perhaps the thing has been put back together wrongly, either the steering wheel put on one spline (or more!) off, and the alignment bodged to straighteb the wheel, or the opposite where something silly was done underneath and the wheel put back on crooked to compensate. Nut there isn't actually much evidence that you have such a problem anyway. It is something you can easily measure and test for to find out though. My money is still on the HICAS CU not driving the PS solenoid with the proper PWM signal required to lighten the load at lower speed. If it were me, I would be putting either a multimeter or oscilloscope onto the solenoid terminals and taking it for a drive, looking for the voltage to change. The PWM signal is 0v, 12V, 0V, 12v with ...obviously...modulated pulse width. You should see that as an average voltage somewhere between 0V and 12V, and it should vary with speed. An handheld oscilloscope would be the better tool for this, because they are definitely good enough but there's no telling if any cheap shit multimeter that people have lying around are good enough. You can also directly interfere with the solenoid. If you wire up a little voltage divider with variable resistor on it, and hook the PS solenoid direct to 12V through that, you can manually adjust the voltage to the solenoid and you should be able to make it go ligheter and heavier. If you cannot, then the problem is either the solenoid itself dead, or your description of the steering being "tight" (which I have just been assuming you mean "heavy") could be that you have a mechanical problem in the steering and there is heaps of resistance to movement.

      R33 persistent issues. P/steering and lag/misfire

      By MissMintyR33 · Posted

      Little update  I have shimmed the solenoid on the rack today following Keep it Reets video on YouTube. However my steering is still tight. I have this showing on Nisscan, my steering angle sensor was the closest to 0 degrees (I could get it to 0 degrees by small little tweaks, but the angle was way off centre? I can't figure this out for the life of me. I get no faults through Nisscan.
