Hi there,

A whistle is more (excuse the pun) in tune with a vacuum leak, i would be checking this first.

With a vacuum leak there will normally be some idle concerns, higher idle or a rough idle, have you checked all the belts for tension and condition? belt grip is not a great idea as the muck is so stick, it will pick up road grit and damage belts, check for any loose or cracked vacuum hoses and check the belts, you can also remove the belts and run the engine, if the noise is gone, it will be belt related.
