R33 Clutch Noise

Our R33 has an annoying noise that sounds for all the world like a drive belt squeak, only it goes away when the clutch pedal has even the smallest amount of pressure applied to it.

It's a series 1 GTS25T if that makes a difference.

If anyone has any ideas what this could be, or how to go about fixing it, I'd love to hear it.

Thanks

Sam

Lubricate the pivot ball and fork. You can also lubricate the shift boot where the pivot fork goes through on the side of the gearbox.....that one caught me out once before. The rubber squeaking on the alloy bellhousing. Usually it's the pivot ball, fork or the actual throwout bearing. Have had good success with just lubricating these components

Sound's like an input shaft bearing. Relatively common in Skylines/silvia's around that age. Also relatively harmless, just a bit annoying.

Big job to replace though.

the line "only it goes away when the clutch pedal has even the smallest amount of pressure applied" would indicate that it's not the bearing as the smallest amount of pressure on the pedal will not stop the gearbox from spinning

Yeah if it disappears by slighting pressing on the clutch pedal, I would say it is the thrust bearing responsible. This action presses the thrust bearing up against the pressure plate, cutting out the noise. I had the exact same issue, sprayed some lithium grease along the clutch fork and on the thrust bearing (don't spray towards your clutch) - has fixed it for quite some time now.

Very common issue in Skylines.

Birds is right... I have the exact same issue, sounds like a twittering noise but when i even just rest my foot so ever lightly on my clutch it goes away, and i've been told it's my thrust bearing too.

      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
