when the car is cold, I hear a noise :cry: (as if there were little stones in headers)when the car is at the idle or when I accelerate and released the accelerator(revs btw 1200/2800).hear the noise very well in interior but not with my head under the hood! what can it be?it can't be the lifters cause,i'll be able to hear the noise(with the head under the hood) if it was the lifters.

what about VTC ? :confused:

after 10mn,when the engine is hot the noise came off :smash:

Monsieur

Je suis désolé mais nous ne pouvons pas tout à fait comprendre exactement ce que vous dites. A pu c'être l'AIV. Que peut faire un bruit le maugrément quand ils sont pleins de l'eau....je pense!!!

A bientot

ah bon. j'agree monsieur, c'est les valves d'AIV dans le wheel arch gauch sur le ZX trois hundred. :slap: :rofl:

Dave ..connaisez vouz le bleeding link a la Forum Techniques?

err.... je m'apelle Daveede

it's not the aiv,i know the sound of aiv full of water.

when i'm sitting in the car,the sound seem to came of the back of the engine(or from the dashboard?)

sorry for my bad english!

its not detonation is it???

no it's not detonation,it's only when engine is cold and beetween 1500rvs/mn to 3000.

i'vnt any error code on the ecu(and with my blitz r-vit type2).

Is it an AUTO?

1000vt

Votre anglais est grand. ..........er mais je ne sais pas quel est toujours le problème avec votre voiture!!!!

Qu'el domage!

no its'nt an auto.

the first time it's happen,i was thinking it's a damage valve noise,but the engine work fine,good boost an perf ,no trouble and has i said any noise after the engine is hot.

That's interesting cos I had a noise just like this at very low idle (too low pro'lly) at 650rpm, coming from the back of the engine around the injectors. As soon as you tap the throttle it goes away, and so far (touch wood) it seems to have gone away after a good long hard drive. Could it be a noisy injector?

don't think its the injectors on mine(and the noise is beetween 2000rpm)

it's like "gringgring"sound and coming from the dash or back of engine,but can hear it only when i'm on driver seat!

any idea for my problem?
