Whistling sound when driving?
Hi all,
Yesterday my Evo V developed a weird whistling sound, not too dissimilar to the sound of a Supercharger? The noise increases with revs but mysteriously disappears as soon as the clutch is pressed? The sound pitch also increases with revs but the car drives as it should? The clutch is an Exedy, recent (less than 1k miles), so unlikely to be that. I don't think it's the turbo as that was recently rebuilt by Owen's. Can't see any leaks anywhere so can only assume it to be an air leak?? Any ideas as to where - Intercooler pipe? BOV connectors?
Many thanks
