Tech Noise when revving car at a stand still

Woette · 30th August 2008, 10:55

Hi,

I've got a question, earlier this day when i revved the car a bit when standing still i heared this weird blowing noise combined with a metally rattle sound coming from the engine bay, sounds a bit like a pump or something. However when you rev by pressing the pedal slighlty that noise isnt there, its only when you give a good short push on the gas pedal. Anybody who might know what this is? A bit worried since the car has to do quite some miles in the next two days.

grtz

edit: its the 1.8 petrol

Have a read of this thread and a listen to the sound clip.

Strange sound

You could get a friend to lift the bonnet and listen for you, might be more obvious to hear where the noise is coming from.

Woette · 30th August 2008, 11:08

No thats a 100% not the same sound, in that clip the engine isnt even being revved.

i did, my dad listened and said it was coming from the engine,since the civics engine bay is so small its really difficult to point it out

I have that sound too (i think). I believe it has sometimg to do with the AC. Turn your AC off and check if you still hear the sound. I will have the dealer check mine at the first service in about a month.

Update on my "sound" - it was leaking fluid from the AC. When the dealer installed the engine heater (or what's it called in english...

) a small leak of some kind had developed with the AC. The dealer stopped the leak, and refilled the AC. Sound is now gone.

I get one that's the opposite. The car makes a wierd rattling sound deep in the dash/engine area, then when you rev the engine it goes.

If you drop the revs back to tickover, it starts up again!

Wheelchair,

Take a look at my comments on the following thread re. a vibration: Dash rattle under acceleration. I heard it at idle too. Turned out brake lines were fouling against each other. They still do, though thanks to judicious use of some self-adhesive foam pads, I don't have the sound anymore

These things are annoying, still at least the car is reliable.

Its the EGR system chattering. Mine does it more when its cold to warm itself up faster.
