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.
