I checked out the common problem list
and I found this one

Problem: Whistling sound comming from engine bay
Solution: Put the airbox cover back on

And so last week I started my s2000 for the first time this season and I notified some sound comming from the engine bay.

check out this video from youtube that I make.
I wanted to know if this sound is the one from the prolem list or not ?

If not what is it ?
I don't remember if this sound is correct or not.

And no I dont have the Air Conditional ON

Thanks
Sorry for my english

 

good video

does it make the sound when the filter is on?

 

That vid made me sea sick.

 

Yes the sound is there even with the filter on

and sorry for the camera is the only one that I have

So any idea of the source ?

The sound is there event if the engine is cold

 

wtf are you doing with the filter off and engine reving???

please dont tell me you ran your car with no filter....

 

mine has the same issue... it's only when the airbox lid is off... then it whines slightly... and for me rpm doesn't increase the pitch of the whine either. Not sure if the noise stays there regardless when you put the cover back on or it just dampens the noise... also it stays noisy even once fully warmed up... doesn't change tone or anything...

 

maybe theres a hose leaking or something? listen carefully for where the noise is coming from..

 

No I just remove the filter for the test I'm always running with the filter on.

I will try to find exactly from where the noise is comming.

Putting the box back is only dampens the noise only but it still there

And one more thing
when I put the cover back I put my hand on it I can feel vibration then reving up the vibration disapear and come back when it goes back to idle.

 

I will check it out

My car is going on inspection next week I will ask to check this out.


If someone have more information please let me know !

 

Its normal...its just your intake. Its louder because you have your lid off.

Its normal. Aftermarket intakes do it as well.
