haha sometimes the pics don't help do they? its a little metal cylinder with a yellow plug on the end, 90o back from the oil filter

1/ Remove the plug (under a dust cover) on the back

2/ Unscrew the sender anticlockwise, off it comes :rofl:

Should it come off pretty easy. I did find it but was having trouble removing - I even borrowed a tool that latches onto the back of it (i.e onto the hexagonal piece on the back) and you connect a 3/8" bar to it. Maybe if I remove the plug it may work better.

I've decided to just do my timing belt first as I don't think the oil pressure is a problem. I wanted to check it in case it was the oil pump - in which case doing the timing belt I am almost at the pump.

Meanwhile since I've played with it a bit I couldn't get it to read much beow the 2 mark on the stock gauge..

Thanks Duncan

You can use a 14mm spanner on the closest side to the block. Easier to get at from underneath and behind the R/F wheel. That is of course if you can get underneath.

On the issue of your oil pump....if you own a skyline, which I assume you do, you cannot remove the oil pump without removing the sump. Do not even attempt to as you will wreck the sump trying and you won't be able to re-seal the pump when you figure out you have gone too far. Also, you probably won't be able to get the timing belt lower gear off for reasons I won't get into, which means that removing the pump will be almost certainly near impossible without either breaking the gear or the pump. If you have any queries PM me and I will be happy to point you in the right direction.

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      I refreshed the OEM injectors with the kit and connected it up. It now ideals okay even with the IACV removed. Driving still has the same cutoff issue like the 550cc injectors so the issue is somewhere else. I bought FPG's Fuel Pump Hanger. I will be installing it next, but it is not as straightforward as I thought it was with my limited wiring knowledge and no instruction on the specific model I purchased (FPG-089). I also got the incorrect billet clamp as I could not find info on the OEM sizing.

      Stop looking at the garage floor, and turn the radio up a bit louder if there's any strange noises...

      Unknown sound similar to BOV on positive boost with partial throttle RB26

      No. Turbo shuffle and surge/flutter are not the same thing. Specifically, on a GTR, turbo shuffle has a definite meaning. On a GTR, the twin turbos are assumed to be the same thing and to operate the same way, exactly. In reality, they do not. Their exhaust sides are fed and exhaust a little differently, to each other. Their inlet sides are fed and exhausted a little differently, to each other. Consequently, when they are "working" they are often at slightly different points on the compressor map compared to each other. What this means, particularly when coming on boost, is that one of them will spool up and start producing extra flow compared to the other, which will put back pressure on that other compressor, which will push the operating point on that other compressor up (vertically). This will generally result in it bumping up against the surge line on the map, but even if it doesn't, it upsets the compressor and you get this surging shuffle back and forth between them That is "turbo shuffle" on a GTR. It is related to other flutter effects heard on other turbo systems, but it is a particular feature of the somewhat crappy outlet piping arrangement on RB26s. There are plenty of mods that have been attempted with varying levels of success. People have ground out and/or welded more material into the twin turbo pipe to try to prevent it. Extending the divider inside it works, removing material doesn't. There are aftermarket replacement twin turbo pipes available, and these exist pretty mush purely because of this shuffle problem.

      You can temporarily* use lock collars to keep it in place until you can do the bushes, back the nuts off, slide them in, snug back up. *temporarily is often for ever

      Thanks for the quick reply. To be clear, when you say turbo shuffle do you mean turbo flutter "stustustu" or referring to something else? I had thought they were the same thing. When I wrote the post my intention was to say it wasn't a flutter/compression surge sound. My understanding was that a flutter sound would be occurring when throttle is released, whereas I can keep the throttle in the same position for this noise
