Hey all, I just got an 02 SiR (K20A3). I haven't driven a Civic in quite a while before this, so I'm not sure on this. I'm getting this light, high-pitched fluttering sound. It's not a rattle, squeal, or vibration; I would liken it to a constant cricket chirp, but quieter.

Some troubleshooting info:

 

Does it change with clutch position? i.e. clutch in, no sound, clutch out, chriping? Sounds like an input bearing or throw out bearing if that's the case.

 

Nope. Clutch position makes no difference. In/out, sounds exactly the same.

If I listen very closely, I can hear the sound progressing upwards and downwards corresponding to the opening and closing of throttle. Also interesting, I can hear it somewhat when I rev in neutral while moving, but almost not at all revving while parked, which makes me think it's just air movement. Maybe this is just the way the intake sounds on this car and I'm not used to it?

 

a video would be helpful. Also check that any splash guards and engine bay plastics are secured. Any modifications to the intake? (Short ram / cold air?) My short ram whistles a bit hahah

 

It never seems to work well without good recording gear, but I'll give it a try.

Will do.

Intake is stock. Everything else looks to be stock as well.

 

OK, the recording actually turned out quite well: Recording of fluttering sound.

 

Sounds like CV axles to me. Jack the car up and give eash axle a solid shaek forward-backward, in-out and see if the rattle a lot. Notice it in the sharp turns?

 

Thanks, I'll take a look, but I kind of doubt it. I just bought this car and it wouldn't have passed inspection if the CV joints were bad. Steering doesn't affect the noise one way or the other.

I was thinking maybe exhaust leak, but I thought those tend to be a lower, more rattle-like sound.

 

CV boots are fine.

If I bend down by the driver's side wheel, I can just barely hear it while it's idling. Maybe it's just the intake?

 

Hello,
From everything I am reading, a clicking when making sharp turns at low speeds seems to be the CV Axle. from the sound of it, it is coming form the drivers side. I am trying to get a hold of a replacement, but none of the parts stores have one in their system. I have a 2015 Accrod EXL V-6. If someone could point me in the direction of a part number and where I can buy it, I would be grateful.

 

Umm.... did you reply in the wrong thread?

 

I did, sorry. I was looking for a way to ask my question and it wasnt until i posted to your thread that i realized my mistake.

 

Haha no problem, got a free bump out of it

 

 

That's good. Make sure the intake is still attached to the engine bay as well lol
