The leak may be there, but hard to say. Your car has quite a few vacuum lines and sometimes it is a challenge to find the leaks. But again - that is what causes the whistling that you are hearing.

Found it! It's the power steering hose that is n the front drivers side. Leaking where there is a plastic connector and 5/8 in bolt.
