Message	Odd sounding whine at idle. Changes tone and it is pretty high pitched, sounds off. These are a new set of JWT550 BB. Basically, what the hell is this and is it normal? 550bb noise

I have 700BB's and the 370 pops, too. - ZaXxon 04:37:10 11/19/13 Did you try with the "regular" POP filters? - ZXoltan 07:59:21 11/19/13 are you sure it's not the bov / recircs - Zvil (FL) 09:01:52 11/19/13 No I'm not, but if it doesn't mean an issue with the turbo - Jkova300z 17:43:44 11/19/13 I would lift the Z and check, that sounds like an air leak - CmyZ 21:36:05 11/19/13 I did a pretty comprehensive boost leak test. Didn't - Jkova300z 22:52:39 11/19/13 Seconded. That sounds pneumatic, not mechanical. (n/m) - ChristopherTheOne 15:48:13 11/24/13
