Whistle noise on cold startup 2018 Sport Tech

ichris · 05-06-2019, 10:03 AM

It's been roughly 37 hours since I last had my Z turned on. This morning I tried it another way. Hold my Clutch down and started the Z. Keep it on till the speedo needles effect finished. Slowly let off the clutch and no whistling.

You're just masking a potential problem. No? I'd rather hear and document it. Try to figure out what that is.

It's not happening to every Z out there, but apparently its inherent. My next guess is clutch then transmission.

mine makes this noise as well. i've driven/ridden other vehicles with a similar noise, i'm quite sure it's the clutch.

i don't have any special knowledge about the Z - i've only owned mine for a few months - but if you look at an automotive-style clutch assembly you'll see lots of opportunity for noise when not engaged. probably it goes away when it warms up simply because when everything tightens up a bit when it gets warm.

my moto guzzi makes quite a racket when cold. i'm far more familiar with motorbikes which is why i'm saying things like 'automotive-style'.

i strongly suspect that every car does this, or would, had the engineers not spent the time to mask it. likely in a sports car like the Z the engineers were less concerned with mechanical noise.

also, i'm in burnaby so hi neighbour.

Have an appointment with Nissan this coming Tuesday. They are giving me a loaner so they can hold the car overnight and hopefully create the noise after sitting for a while. Fingers cross.

Make sure you leave it for a COUPLE cold nights, OUTSIDE. Usually dealerships have tents or covered areas in their lots.

I also made sure I was present the day they wanted to do the start, and to start it in my presence.

A pain in the a$$ and hard to get schedule to fit, but it's worth your while.

These dealers will simply not believe you or your videos etc. Their hands are tied by Nissan, because they wont get paid if they can't prove it. Either by physical evidence or multiple witnesses. In my case, service manager and two mechanics.

Good luck and PLEASE let us know what they come up with.

Thanks

The Nissan service center just called. It's the throw out bearing and CSC what is causing the whistle. I tried asking them if I get the Zspeed elimination kit can they install it. They said I would have to talk to manager, but if anything goes bad they can't warranty it. I'm praying they have a newer CSC. We will see. I guess when my warranty runs out I'm going to Zspeed route.

Yeah, they replaced my CSC and pilot bushing. The noise has come back. So it wont fix the problem. That might not be the problem/sound.

The CSC is prone to failure and/or leaking. Never was known to make a noise problem. It would cause the clutch pedal to be stuck or no actuation if you lost all the fluid.

I don't think they upgraded the CSC, but may have improved manufacturing process. Cant say for sure.

I'm going to drive on this second CSC and make more notes of it. See if noise is consistent again.

I wont do CMAK till warranty is over.

They have not made a more robust CSC.

I don't trust Nissan to install any aftermarket parts. My dos centavos, find a good transmission shop - not a chain, tho. I did some googling and drove around until I found a shop with a pristine '57 Chevy and an immaculate surplus HMMWV parked outside. Figured they must have a good reputation and I was right.
