    Default Weird Whistling sound??

    I was driving the car today and I started hearing a weird whistling sound coming from the engine bay. i turned off the radio to listen and whenever i put any kind of load on the engine (even barely touching the gas) and im in 3rd, 4th, or 5th at about 2000rpms it starts to whistle and it gets higher pitched with the engine. its not the turbo.

    could it possibly have something to do with the clutch/flywheel? i was goin about 40mph in neutral and blipped the throttle to shift to 4th without using the clutch and as i was slightly pushing it into 4th the whistle was there and it got lower pitched with the engine speed slowing down and then it went it gear like normal. then putting load on the engine caused the sound again.

    any ideas?

    also, when in neutral with the foot off of the clutch the clutch/flywheel has been makin a lot of noise lately. more than before. it used to a little bit.. then after it was broken in it only made a little noise when the a/c was on. now its considerably louder..

    The only thing that should(not that it should) make noise on the clutch is the throw out bearing. Does it change when you depress the clutch pedal?

    Is it possible you have a small air leak?

    the whistling only happens under load, so when its in neutral or the clutch is pushed in it doesnt make the sound..

    and the noise with the clutch does go away when you push in the clutch. some people have told me its just the lightweight flywheel so i dunno..

    all of the vacuum lines are fine too..

    ok so i just went for a drive and it is still doing it. i wanted to mention i cant hear it when the window is down, only up and its pretty quiet.. i also noticed that if i shift front 3rd to 5th its makes a kind of whistle for a second too (sounds kind of like a person whistling quietly while humming if that makes any sense). does that mean it has something to do with the tranny? could it be a t/o bearing? im 99% sure i replaced that about 4000 miles ago..

    I don't think the throwout bearing would make that type of noise...

    I had an Ranger years ago that made a sound similar to what to you describe.

    It turned out to be a problem with the heater core. The coolent flow is relative to RPM's so as the RPM's climbed the flow through the core increased making the sound.

    It sounded like the trans was going to blow up but wasn't the trans at all.

    It's not likely to be your problem but it is one more possiblilty that is fairly easy to eliminate. Just by pass the heater core and see if anything changes.

    Sounds can echo through a car and be misleading. For example one rear shock bolt just slightly loose enough for the captive washer to rattle sounded like the entire subframe was about to fall off.

    its not the radio,,,, i have a 07 zx3,, same sound only under load and at around 3200-4100 rpms,, sounds just like a turbo spoolling up.. high pitch.. clutch makes no diff.. a/c on or off no diff. i have tracked it down to the intake.. but can not find where it is... maybe to swirl valve ??

    same issue here. I noticed it once I put my cool-flo intake on. When getting in higher rpm's it starts to whistle. Maybe because of the itg filter

    It is the intake, mine does it when I get to about 3000 rpm. it didnt do it until I put the intake on my car.
