loose thin metal sound

[SeanZ]

i got a 05 sti and everytime i come to a stop or mostly when im not accelerating as much i heard a rattling noise of thin metal its getting louder now so i stopped driving it... what could it be?

From what part of the car does it sound like its coming from?

 

[SeanZ]

the engine but i cant tell where because when i come to a stop it doesnt make the noise anymore also no cel

 

[Alin]

Could it be that you have a turbo heat shield not bolted in all the way?

 

[SeanZ]

its all stock and its never made the sound since i bought it till yesterday

Wow thats random then. Pop the hood and have someone rev it a little bit see if it makes the sound again.

 

[SeanZ]

ya thats the problem it wont make noise unless the car is moving lol

 

[Alin]

Well if youre slowing down... Brakes?

Other heat shields that I'd take a look at would be on the header, up pipe and down pipe.

How fast do you have to be going for it to make the sound? Is the sound related to engine speed or car speed? Have you done a full visual of the engine bay, wheels/brakes, and under the car?

+1 for a heat shield loose or cracked. My up pipe heat shield is actually cracked around the top and rattles while I'm driving, but not always at idle or certain cruising speeds, just depends on conditions/vibrations. Something I'm gonna try to fix this weekend...good luck!

Glad you found the issue! Good luck on the fix and let us know how it goes! :tup:
