I'm trying to diagnose a noise that I'm consistantly hearing when my integra is cold, when I hit 3500rpms it makes a whirr sound. It goes away after the car drives for a bit. I checed for loose bolts but I can't find a source. Any help would be appreciated. Thanks!

 

i dont know your exact problem, but i recommend staying under 3k rpms until the car is nearly warmed up. Engine wear is most apparent when starting a cold engine and running a cold engine hard. So to avoid this noise, keep the car under 3k rpms until it is fully warmed up.

 

whats it sound like? that would help

 

does it make the sond when u r driving or parked revving the motor and whats done to the gsr motor

 

It seem as it only makes the sound when driving, motor is 100% stock.

Sounds like a metal vibration, should I not worry about it? I drove it this morning keeping it under 3k till it warmed up and had no problems.

 

Sounds exactly like the sound I have in my gsr. Although mine doesn't go away, It's been doing it for 3 years and never had a problem. Everyone seems to think that its something with my heatshield, so no big deal.

 

mine rattles at 3100rpm and i think its the heatshield after the cat converter.

 

most likely heat shield or header had the same problem end up being the stock header..

 

Yeah I'm willing to bet its definitely the heat shield.

 

is it like if u are at 3.5 driving and sitting ther revving cause i have lsvtec and it was a gsr befor motor swap did it before swap its like a horrible rattle but if u go over 4100 it goes away id say heat sheild but all of mine are llready off so id say header mines been doin it for monthes .solution =aftermarket header

 

sounds like the infamous gsr rattle. Here is the most probable solution.

its the "A"pipe. its the first pipe from ur exhaust manifold to ur cat converter. acura has a bulletin out on that. the bulletin says to replace the "A" pipe. not sure what the warranty is but check it out.

 

yea just as well could be. i checked the exhaust heat shield and the heat shield around the cat and they both arent rattling. I wonder if they cover it under warranty...
