2002 Acura RSX Rattle at ~3500 RPM

2002 Acura RSX Type-S w/ ~93,000 miles.
As you can hear in the video, there is a rattle that occurs when lifting the throttle @ approx 3500 RPM, and continues to rattle as it decels below ~3200 RPM.

This rattle occurs intermittently at low RPM's in all gears, typically at low speeds. However, this rattle is most easily reproduced by lifting at ~3500 RPM as demonstrated in this video.

Some usual culprits were identified and ruled out. I removed the half-shaft axle heat shield, to no effect. I also removed the plastic VTEC cover, also to no effect. The exhaust manifold heat shield felt solidly attached when pushing it by hand.

it's the heat shield

tighten the screws thats it

[howheels]

I checked all of the heat shields, and even removed the half-shaft heat shield.

Do you issues with clearance with an aftermarket front strut bar? Or did you relocate your front license plate? Those were problems for me, but an easy fix

[howheels]

No, everything is totally stock! The front license plate is actually not there (wasn't there when I bought the car).

My G37 has the same sound pretty much. Did you fix yours?

I am going to dealership in next few days and mention loose heat shield to see if that fixes it.

Check the timing chain tensioner. Manual says nothing about it but they tend to fail around 100k easy part to replace. Hope that helps

this is exactly the sound my car has been making, i just posted a video today. but mine is at 1500rpms. PLEASE tell me you found out what was wrong with it. it's driving me CRAAAZY!

[jrus1]

It's most likely the FLEX GASKET in between your header downpipe and where the cat meet.. I have something similar , but not as bad as yours.

check that out..

[cocx88]

maybe its a broken mount, cuz rsx come with weak stock motor mounts

[hondaftw1234]

Tighten the heat shield. Happened on our 04 honda odyssey. Honda was going to charge us like 300 dollars but we went to a local mechanic and they fixed it for 20 bucks

@howheels

Have you checked your plates around the Cat converter? I had a annoying rattle on my 2002 RSX at around 3,000rpm but later fixed that by tightening up a bolt to the heatshield underneath the car.

[ardinozos]

[MaddDogg81]

the header or a mount?
