Engine: Jingle Bells
 

That's what it sounds like along with some whistling. Sounds like one of the pumps is on it's way out. The sound is at idle and comes from front right, around the area between the intake manifold and the air-box. H20 pump?

Sounds like the issue with one of the air intake hoses having a crack in it. There is another thread somewhere on here about it. I have the same issue, just have not had time to fix it.
