What do you think it's there for?  I can tell you from experience
that when driving down the road there's enough positive pressure in
the engine compartment of a 2.1l to lift up an engine cover that's
merely covering the hole so that it vents into the vehicle.  And by
lift up I mean an inch or two.  I had to weight it down (I was doing
some sort of diagnostic with wires running into the compartment)

Yours,
