Just a hunch but has anyone checked if the hood is touching the headlamp lens when you press down on the hood just above the headlamp?
There are 2 large round pads on each side of the radiator that are adjustable and control the position of the hood when closed. Everyone should make fine adjustments as there's huge variation from factory.
Screw them down all the way and you can see a little gap to the hood if you shine a flashlight. Unscrew them up a few turns at a time until they barely touch the hood when closed. The correct height would be 1 or 2 turns up from that point, no more, no less.
EDIT: A strip of weather seal foam (closed-cell) on the hood edge (headlamp area) should take care of this issue as well.
