So i just took my Evo out from winter storage and i noticed when its idling i can hear a whistle sound from the engine bay some where i cant pin point where its coming from. I also noticed the whistle/a wine when im driving slow before boost idk if there the same thing or unrelated. But if anyone has any ideas as of what this could be id appreciate it, im new to boosted cars (i know the normal noise of the turbo boosting tho)

Thanks

 

Oh and car is pretty much stock, besides injen intake by the PO. I put a turbotimer in this winter and some gauges but i havent hooked them all they way up yet kuz ones bad and gotta send it back. I did hook the boost one up tho and it doesnt read anything but that's a separate issue

 

check the throttle body for leaks. could be a sign that they are toast and/or need new ones. my car made a whistling noist while driving right before boost after i replaced the seals. after a few weeks of driving (boost leak fixed!) the noise calmed down as the seals began to sit.

other than that check for leaks (exhaust, IC etc) esp by your intake. gl

 

Alright yeah idk if its the Tee for the boost gauge off the but all that seemed tight im gonna take it all out again and make it just stock kuz it didnt work anyway. and i had an exhaust leak but it was way in the back just to the tail pipe i fixed that but i still got the whistle up front. it sounds like its right up front my the manifold so that could be it just hard to tell

 

Narrowed the noise down to it coming from this general area..

 

^^ wastegate? maybe?

 

i have a feeling its your turbo J pipe gasket. mine whistled when it was leaking big time

 

lol maby its your turbo and u cant hear it in boost because of the wind

 

What do you mean by turbo, that its bad or something?

 

How can I tell?

 

I had a whistling sound when I hooked up my 9 BOV. The problem was I did not tighten the hose down under the BOV and it had popped off.

Your noise is not that area but the point was I had a leak, a big one

 

Yeah i put my ear right up to the BOV and i tightened all the hose clamps i could and i still here it but i think im just gonna get a smoke test done....

 

turbo whistle search it

 

Do you have a link? Kuz I can't find anything that sounds like the same thing as what your talking about.. Is it atleast normal? I dont think it is kuz it just started doing it

 

Heres a clip of the sound. Can hear the whistle best at the end of the video..
