Horrible Sound When Revving With Clutch In

Hey,

I have this really irritating problem, if I rev the engine over roughly 3000rpm with the clutch fully pushed down (ie. disengaged) I get this nasty whiney noise that pretty much doesn't stop until I re-engage the clutch.

Does anyone know what this might be, is there a simple way to fix it? Or do I need to explain things more. I can probably take a video of it too.

It drives me nuts. :P

Thanks!

Does it make the noise while in neutral, foot off the clutch @ 3000rpm+ ?

No it does not, only when the clutch is pushed down.

Here is a video of it:

First few revs, foot off the clutch.

Then I rev with my foot pushing down on the clutch and the noise starts a bit.. do it again and the noise doesn't stop, even when revs climb down to idle.

The noise stops once I take my foot off the clutch near the end.

Dude, it does it when I'm shifting, so if the revs were going to fall off from > 3000rpm it will make this annoying sound and it's loud and embarassing.

Please don't tell me to take my revs over 3000rpm when I'm driving :) That will make me cry.

Well, you didn't tell us that. You said:

"if I rev the engine over roughly 3000rpm with the clutch fully pushed down (ie. disengaged)"

That suggests to me you are doing it deliberately.

It sounds like it might be a dud thrust bearing.

usually the thrust bearing would make a cricket sound when the clutch isn't being pushed before it got this bad....... did you notice a sound of a cricket while in neutral at the traffic lights or while warming up the car???? I had a similar prob in my r33 gtst, changed the clutch and all that and it went away....

it will be your thrust/throwout bearing. it seems unusual that you would get a new clutch installed and they didn't change the throwout bearing.

yeah it is very strange but it sounds right...... if it is the bearing then don't get them to do it again or demand it free if it looks old...... otherwise dont know what else it could be without looking at it...

Mate, just wondering if you've fixed what wrong?

I have the similar problems just recently. When i clutch in and give it some throttle, the revs would just stay there at won't drop. even when i take my foot off the clutch the revs still doesn't drop. and like you said, I could hear a nasty noise when the revs are high-ish with the clutch in. cheers

      Not that I know from experience, but in theory you'd want your gate spring to be as close to target pressure as possible, so you'd go with the higher gate spring?

      Before I commit to it as I already have the wastegate off the car, would you change it to the 9psi spring instead of the 12, or whack it back on now and try your suggestion?   Edit: Actually I might just swap the spring and see what the logs say after another few pulls, as we know it's still spiking without the Mac valve in the picture so I need more data without the Mac valve trying to combat the issue.

      Sounds good Hmm suppose the main thing is, how much do you care about this car? The filler doesn't make for a very good water barrier lol. If there was a tiny little bit of rust forming now, that in 3 to 5 years time becomes obvious under the paint (starts to bubble up), would it bother you?

      I already have the ability to datalog the voltage... what I can't do is correlate it to what the gauge is showing when I'm looking at the data at a later date. Or something like this. Except getting the oil to 125C+ involves me going 200+kmh at the track so you can imagine this is a little tricky unless I do something like note what the voltage is when I am at the top of 5th gear so I have a point to reference on. Drove car today. O2 still reading richer because hopefully not a leak instead of massive restriction I've introduced. Car really doesn't sound like a LS. It's quite strange. Pulled a bit of fuel out up top. This does potentially explain why my spark plugs looked like the car was running pretty over-rich. If I was tuning it to a ~12.7 which in reality was far richer than that in the past. It will be handy to have the dyno WB to compare my WB to to compare notes that's for sure. At this point I'm happy to just sit in the passenger seat and tune the thing given I've got about 7 million hours on the platform lol.

      Infiniti Q60 Navigation Update

      Yeah I understand you have to pay for an updated map or subscription service or something. But I can't even find a current map for Australia. My map is dated 2017, but didn't this car version still sell in Australia until 2021?   Also, just as an aside, the navigation system warns you of traffic incidences ahead.....why would they include that on a map they knew is not receiving live information. I am forever going to be warned of an incident that probably existed for 30 minutes 8 years ago.
