i know this isnt very specific, but if any of u have had this problem or something like it please let me know. Once inawhile when i starrt my car i hear a rattling noise coming either from under me or towards the front i guess within the engine. It's starting to become for frequent so im getting worried, thanks for ur input.

 

ummm, yeah, we need more info.....how long does the noise last and when does it do it? like does it only make the noise at certain RPMs? what about in neutral?

 

ok well i drove it around again today to hear it, it seems to only occur when im at rly low rpms around 1000-1500 and it sounds as if some kind of metal piece is loose and it's rattling against something. If u have any ideas please let me know.

LOL I have this problem a while back when I owned a LS. GO to any places and they'll cut off a piece of metal that's loose under your car. It's somewhere under teh driver on the muffler.

 

Its probably your heat sheild that goes around your cat just take it off

 

hey thanks alot guys that makes me feel alot better.. atleast its not a really serious thing. thanks alot!

you have wayyy too much time on your hands!

good luck GSRerrr, and let us know what you end up doing!

 

maybe it's something stupid like the heat shield to your cat... like mine... just go under the car for the initial inspection..

 

well i juss went under my car and checked, the heatsheild doesnt feel like its loose at all.... any other ideas to wat it could be??? it usually rattles at low rpms on cold days or when the car starts, or moves very slow.. i'll prolly go check again some other time, but in the meantime i want to know if its anything serious?? thanks alot in advance

it doesn't necessarily have to FEEL loose to be loose. I know mine was loose, and rattling like crazy, but I could not move it loosely with my hands. I just had a shop replace the heatshield.

 

hey thanks, well that sounds like good news, but i want to know if it isnt the cat is it anything serious? up

 

i got a 94 gsr .. mines make a rattling noise everytime the car revs pass 3k and stop at 3.2k .. maybe its the same problem ?

 

got 97 gsr, same sound, bugging the livving **** out of me, especially when u drive girls around.= (
Anyways, if its a loose heatshield, wouldnt it always vibrate when the car is on? instead of only at certain rpm, or if its a hot or cold day?

No, The RPM's cause different frequency's of sound which makes things vibrate. Like on my drumset, When i hit certain drums, the snares will rattle while when i hit some other drums, they wont. Or Bass in a car. Some bass pitches will make the lisence plate rattle, while others dont.

I have personally had three rattles in my car. The first and most annoying is the Infamous "curse of the GSR" The rattle that happens around 3000-3400 rpm's. It is in the Header, so once you replace that it will go away. I dont beleive that is in the heatshield.

The next happened in high rpm's (vtec) and was somewhere in my stock cat-back exhaust. I replaced that with my friends old GSR exhaust and that rattle went away.

The third was more or less a grind, and was a bad transmission bearing.

If the rattle is tingy, it is more or less jus something loose, like a heat shield or the header problem, or somethign like that. Where if it sounds internal, it could be your transmission.

 

well it sounds like thin metal hitin against other metal, i dont think it's the header because i juss put in a comptech header, so u think its most likely the cat? i'll check everything tomorrow but i jus wana get ur opionons

 

mine 94 gsr does the same damn thing. Other people were saying that it is the Lost motion assemblys. I think im gonna try some slick 50 or lucas or somthing like that to see if it stops rattlin.

 

jebus!, i dont know where to start fixing my car, new headers, or cat, or heatshield, or valve spring, blah!!!!

 

I have the same sound when im idling. I can only hear it when im outside the car. Reminds me of an empty can with the tab inside rattling around.

 

Have a rattling noise that is very similar. Told it is the heat shield on the cat. One of the most common problems with Integras. Take it off, and don't park on any high dry grass or leaves and you will be fine.

 

does it rattle when u press down on the clutch or does it go away?

 

is there suppose to be a heatshield on the cat?? mine is just on the piping to it and form it.

 

My friends Integra was the same way
His was a 93 ls, when he Idle you can hear a rattling sound.
You should check your alternator belt, its prolly loose, if it is then tighten it.
