so i just bought an 05 mr with 19000 miles on it. whenever im in second gear or higher and the rpm is above 2k, i hear this weird noise that sounds like its a bad timing belt, but i dont think it is, heres why. it doesnt increase in noise or frequency when i gas it, it just stays until i come to a stop or am in first gear. any idea on what it could be?

 

Congrats on your purchase and welcome...
Do you have an intake?

 

no intake, completely stock save for a turbo timer. ive noticed that this noise is on and off

 

Does it increase with rpm?

 

nope, the noise stays the same, doesnt get louder or higher frequency at all with the increase of speed or rpm. i thought it was the timing belt at first, so i opened the hood and reved it a bit and it sounded fine

 

Is this car stock or modded? Can you describe the noise with more specific detail? Where do you think the noise is coming from?

 

well the car is stock. soudns liek its coming from the engine bay. and the noise doesnt get louder as i speed up or give it gas. its almost like a squeaky noise, kind of like a bad timing belt but not as bad. im having trouble describing it.

 

Not radio frequency is it? After market radio and something shorting out?

 

nothing electrical, it's definetly coming from the engine bay. It almost sounds like a cricket making noise. Doesn't change in volume or pitch. Could it be my belts or pulleys? Possibly the tensioner?

 

Make a video

 

i can try, hopefully youll be able to hear it in the video. in the meantime, does anyone know what it could be? should i just take it to the dealer and have them look at it?

 

If it's stock, you have nothing to lose. Try it out.

 

true, ive heard of some other members having this problem, and they say its the serpentine belt or timing belt possibly being glazed. could that be it? cause the problem isnt obvious when the car starts up. if so, how much would it cost to replace belts and pulleys? and in the meantime ill try and make a video of it

 

Well with only 19k miles I wouldn't think the belts would be going bad yet, but anything is possible.

Make that video and up it here so we can see and hear it and maybe get a better idea.

But the dealership should let you know what's wrong.

 

My timing belt makes a LOT of noise. Sounds like the motor is knocking. The first cold day I ran my car, I thought I had spun a bearing until I noticed the sound coming from under the cam gear cover. It goes away when the car is warm.
