    Strange whistling sound from the E38 engine... Whats causing it?

    My E38 BMW 7 series makes a strange "sissle-sissle-sissle" sound.

    1. Any ideas whats causing it?
    2. Can it do any harm?

    pcv plate. back of the intake.


    ***edit*** that's a six cylinder car, and I didn't hear any whistling in the video on my phone... cyclone valve most likely.

    Sounds to me like the runners, bad gasket(s) underneath.
