Whistle noise on cold startup 2018 Sport Tech

Bubbaloo · 06-19-2018, 10:05 PM

Hey guys/gals. On cold startups usually in the mornings I get a somewhat loud whistle type noise and then when I press the clutch once it goes away almost completely. Weird. Is this normal?

Do you drive you car daily? Mine stays in the garage and if I go a few days without driving, it makes a slight chirping noise for like 2 sexond, but if I cold start again after a day of driving, then it doesn’t do it. Car only has 29k miles.

Yes. I do daily drive it. But yes it does happen more than so often on cold (2 days have passed) starts.

Any fix? any concern?

YES. 2017 NIsmo. I had this happen last year. EXACT same symptoms. 2 days resting and cold start, a whining noise. Would go away once clutch was pressed. Would not occur on DD and warm days. Comes back like clockwork after 48 hours and cold start or cold days.

I was under warranty, so they changed the CSC /release bearing and Pilot bushing.

Seemed to have fixed it.

Advance to 2019 and few weeks ago. Noise has come back!

While they did the CSC, I had them replace the tranny fluid. They told me it was a little dark, but ok. No metal.

No shifting issues or clutch issues however.

I'm guessing something that gets lubricated has it's oil running out after sitting for 24-48 hours. Just a guess.

I have a dozen phone videos, I have to see how I can post them up here.

I noticed mine today. Around 60-70° cold start morning. I stepped on gas and whined harder. It sounded like from the exhaust system just under the shifter. 30-40mins to work. Gone. Start up during lunch. Nothing.

From what I have been told by techs and other Z owners, this is quite normal on the 6 speed manual. Apparently our transmissions are inherently noisy.

The solution to your problem is to get a louder exhaust. Then you'll never hear that sound again.

Yes, but that is another issue/inherent noise. I know what you are talking about.

This is a momentary sound that goes away with clutch actuation. Never to be heard of again until resting for 48 hours.

I own a 2016 sport package 370z with 37k miles. I have the exact same whistling noise issue. It will only happen during a cold start, and if I rev the engine it gets even louder. As soon as I press the clutch once the noise is gone. I don’t daily my car either.

Our girls need lots of lube.

It’s a lil over 22 hours since I last had the car on. When I started up nothing. Then that howl/whine started. Press the clutch in and slowly let it out. Gone.
