Hey guys i have a 2000 Em1 and i have been hearing a whistle/scratching noise from my car.....it only happens from 2-4k rpms, moving or not. Anyone know what this could be?

 

it's your intake, especally if you have a short ram intake and high flow filter the noise is amplified

 

pop the hood, rev the motor from the TB and listen for it. i would bet its your intake as well.

 

x2 for intake

 

Rick Rabies is stuck under your hood, and he's making turbo noises. That scratching is him trying to get out.

 

lol

 

I just put on a full cai and this noise was happening before I put this on....

Its almost like a screeching noise I think its coming from a belt I really don't know

this noise is not consistent.....

 

souds like possible the alternator or power steering belt then. is it when its cold more then hot?

 

well, my intake only makes noticable noise on startup really.

 

its both hot and cold

 

If it's the belts slipping you can tighten them. Also they make a belt conditioner that reduces squeaking. You just spray it on the belt while the car is running it works great.

 

How do I tighten them?

Whats the name of this spray?

Thanks for the help.

 

go to any auto store and ask for belt conditioner. Something like this http://www.jcwhitney.com/jcwhitney/p...9&zmap=16544G#

To tighten them there is a tensioner bolt on them. I don't know how to explain it usually i just kinda loosen things up until i see which bolt is holding the tension and then go from there. It's pretty easy to figure out once you start looking at it. It is most likely the alternator, power steering would be noticeable because it would do it mostly when turning especially at slow speeds and I doubt your using ac right.

 

I went to the auto store...

I was told it might be my water pump.

No I am not using my a/c I live in WI hehe.

 

I never trust auto store clerks anymore. Have been f-over too many times to trust them. I would not use belt conditioner sprays, but I would re-tension them. Buy a manual for your car if you haven't already, they do help a lot.

Depending on how many miles are on the car when the last time it was that the water pump and timing belt was replaced, determines if I would switch those out.

Most of the time, the belts either have an idler pulley (an extra pulley wheel that pushes against the belt to tension it), or are tensioned via being pulled taught by the driven device (such as the alternator being on a pivot joint). Either way, its fairly simple to figure out how to tension the belts, just give a quick look over.

 

I went to high school with the guy I talked to...and he knows Honda's pretty well.

I haven't had the car long enough to know if the timing belt was replaced. The car has 110k on it, If it gets worse I will get them replaced, but i will tighten the belts first.

Thanks a lot everyone.

 

mine makes a whine type noise at 2300-2350. Ive always just overlooked it.

 

At 110K, if the timing belt and water pump haven't been changed, they really should be.
