Alright soo...I just bought an 03 Rsx-S from my bro about a month ago..Love the car but there is a loud rattling sound at around 1800-2000rpm. Drives me crazy. Thought it was the intake manifold cover so I bent it up so it doesn't rattle on the manifold. Checked Cat and Exhaust manifold heat shield which were all tight. Heat shield around the axle was tight too. Still rattles so I'm stuck. Any DC5 owners out there ever had this problem? Car has 77000 km. Thanks for any help!

 

does it have a race header?

 

Sorry Forgot to mention its all stock..Except My 10,000 ft GT Wing!!! Jokes

 

automatic or stick? does it make the noise in neutral

 

Its a manual. Does not rattle in neutral. Only when it has a load on it for example starting off in first or second at 1800-2000 rpm. But if I rev higher and maintain a higher rev than 2000 and let off the clutch it wont make the sound..Just at the certain rpm band under load.

 

maybe your motor mounts? or something could me loose inside your car. where is the noise coming from?

 

Take the IM and coil pack covers completely off and check again. Or have someone hold the rpm and look/listen in the bay.

 

same with mine...except mine is auto, weather has been too cold check out. mine happens while in neutral and when on idle, its annoying i cant wait till its warmer out

 

Yeah you could get some aftermarket motor mounts and then your dashboard would rattle...instead of your engine.

 

i rather dash rattle than engine rattle, the engine rattling makes my car sound like a beat up buick or oldsmobile

 

Get some motor mount inserts is what I meant.

 

yea it only rattles under load when taking off. sounds like its from left side of engine from the drivers point of view

 

mine does the exact same thing man, it sounds like a bearing chattering from the transmission, only i dont feel like pulling the trans to replace a noisey bearing, maybe when i do the clutch...

 

My 02 type s does this occasionaly. More so after I replaced the clutch. When the weather warms I'll check out the motor mounts and see if they are loose/worn out.

 

Ya I just bought the car a few months ago..So this just drives me nuts..Makes my car sound like a piece of ****

 

there is a heat shield on the right half shaft loosen all the bolts and adjusted the shield to one side away from the exhaust then retighten. there is a service bulletin for that noise

 

my money is on the cat heat shield, its a 3 layor shield and as it rusts apart, the inner layors rattle against the cat....I just replaced my wifes cat heat shield on her rsx....big pia and about 120 bucks in parts.

 

i dont know about you guys but i got a weird rattling sound too, it seems my hood latch is loose cause when i put my hand on the hood to hold it down the rattle stops, lol but i dont think my rattle fits the description everyone else is giving, but im putting it out there that if you dont take care of that hood latch you may have a loose one just like mine ... lol : )

 

A friend of mine with a Type-S had a problem with rattling and it turned out to the A/C line vibrating on the hood. He was boosted though, so I don't if that affected where the line was placed or what but maybe that could be a solution to someones rattle.

 

I have an 02 RSX that has a rattle as well. I thought is was the catalytic converter shield, but three hose clamps hasn't fixed it.

The problem is that it doesn't really make a noise when it's sitting still and the engine is revved. But it DOES rattle when under the load of taking off in first the 2 - 3000 rpm range. It's been hard to diagnose because it only seem to happen when it moving.

One shop seemed to think it was the timing belt guides. But it was going to cost me $350 just to find out if their guess was right. I haven't taken it back there.

Anyone who has solved this problem, it would be great to hear from them.

 

get motor mount inserts and your car will handle like a beat up buick or oldsmobile in neutral

 

noticed mine rattles alil at idle on my 06 and i have a full exhaust and JR race header? do they tend to have this problem?

 

The car is stock.

 

is it a rattle or a studder? Does it do when you hit bump? Is it a high rattle or low pitch? if its low then yeah its your motor mount bushings going out. I got a new cluch put it on mine and the noise when away for awhile, now its slowly coming back becuase I think its getting old. Be careful though, if that rattle turns into a studder, then your clutch is going out, that's what happened to mine. I am on my third clutch. This car just has so many issues.

 

I would classify it has a low pitch rattle. Not when I hit a bump though, just when I take off and shift in the 2000-3000 range. I just had a new clutch installed and it was happening before that. I will check the motor mounts.
