soo i just started to notice a like high pitch "playing card on bicycle spokes" noise coming from my engine. the only time i hear is tho is when im hittin the gas... any idea. my dad kinda wondered if it was coming from my short ram air intake.... yall got any idea what this noise is comin from.....i think its kinda of a dumb question but my dad was wonderin if i was have to tune my car since i put on a new air intake and a the jet mass air flow sensor.

 

my 07 lt did the same thing. but it started doing it when it got colder outside. but mine was constantly, not just when i pressed the gas. but i never found out what it was, i traded it in few days ago.

 

ya thats what i just noticed it tonight and and its cold out

 

sounds like it could be your valves. what weight oil u using?

 

5w-30 thats what the book for the car says

 

hmmm. in all honesty i would have to look in your engine. where does it sound like it's coming from?

 

i think its just bc of the cold weather

 

haha well when im in the car it sounds like its comin from the right side of the engine department... ya not so helpful soo i had opened the hood and listened for it and had my dad rev it for me... and its harder to hear it.. u can only really hear it when your driving down the road.of course. haha now that i think of it u think it could be maybe a exhaust leak from like the downpipe maybe...

 

i got like the same nosie on my 2.2 and idk what it is

 

u think if i took it to the dealer ship they would have a chance to find out what it is

 

eh if your not under warranty, may cost ya just to have it looked at
id look to see if there was anyone else that lived nearby who owns a balt and see what they think.

 

timing chain tensioner collapsed maybe? did it on my 07 ss

 

ya i have a guy who works there says he could look at it for me and not charge me and since i dont kno where the chain tensioner is ill tell him about it and see what he thinks...........better yet where is it located and how do i kno if it collapsed

 

its prolly just from the cold. my aveo does it in the winter too. mine goes away after the engine has been warmed up for a good while.

 

It's most likely your timing chain tensioner, is the noise coming from the left side of the engine? I just started having the same ticking noise, i guess its pretty common on the ecotec engines.
I have 45,000 miles as well.

I ordered the updated one from crate engine depot, ill be installing it soon and doing a how to, if it fixes the ticking then your in luck!

 

i have the same thing on my 2.4 i didnt notice it until i put my intake but then again i didnt know if it was there before because it was winter when i got the car so i didnt really open the hood and examine anything until it was a little warmer which was when i put on my intake. everything seems to be fine though ive had the car a year and the intake probably about 9 months and no problems so i dunno maybe its normal but i only hear it when i open the hood if u hear it when ur driving then it might be something different your talking about.

 

Had a similar sound I found that it was coming from the blower fan for the heater.

 

Without hearing it could be so many things. Does it go away when it's warmed up?

 

oh let us know. mine does it all the time,warm,cold ALL the time

 

it only does it when im on the gas warm or cold and ya diffently let us kno about the new timing chain tensioner

 

Ive noticed the same thing on mine 07 2.4L mine does it all the time too could i possiabley be something serious like in the future

 

Injector Tick?? Common on 2.4's

 

injector tick is common i guess on the ss/tc due to direct injection, it shouldn't be that way on the 2.4, but ill let you guys know soon as it gets here.

 

i kno it aint the injector ticking that was my first thought but its diff not that those are 2 different distinct sounds

 

how many miles?? take it to the dealer
