Hey HT, just wanted to know if anyone can identify this noise coming from my engine. I've heard it on a few other civics of the same type so i think it might not just be only my car. Mine is a 2000 civic EX auto (EJ8), I can try to the best of my ability to describe it:
-First, its like a metallic rubbing sound (metal rubbing metal)that almost sounds like a serpentine belt is slipping (they're not i checked)
-It sounds to be coming from towards the back right of the engine bay.
-Its most audible when car is cold and either; idling, driving at low throttle from 1900-2600 RPM, or when A/C is on.
-Its been getting more audible very slowly over the past year and a half
-I think i can hear it best when the engine itself is vibrating the most

Its kinda annoying and i just wanted to know if i could fix it. Let me know your suggestions and i'll hopefully find out what it is.

I can take some pics if needed just let me know what you want a pic of

Please any advice is good advioce no matter how stupid it actually is. haha

Thanks in advance,
Nate

 

bump, hopefully someone can give me some ideas

 

sounds to me like it is a bad idler pulley. I have the Same problem on my 99 ex and I just posted about a fix. http://www.tegger.com/hondafaq/tsb/civic/x00-003e.pdf should help you out

 

motor is stock?

 

if you think the noise is coming from the belt area, why not take one belt off at a time until the noise goes away? once you see which belt the noise is coming from try spinning the pulleys to see if anything feels crunchy. if the noise doesnt go away at all with all belts removed it could be coming from under the timing belt covers..

 

motor is mostly stock, installed in bay are: CIA, Header, plugs, wires and a few other things but the noise was there before those.

Thanks for that PDF HOUSTONb, i'll def check into that.

jdeemseerx, i can try that too if its not the idler pulley. I don't think it is the actual belt though because to me the sound is similar to the belt rubbing sound but it defiantly sounds like more of a metallic rubbing than a belt.

 

what i meant was to remove the belt..see if the noise goes away.. then while its off you can feel the bearings in each pulley to see which one its actually coming from.
