Where is the freakin water coming from ???

When I bought my duster it leaked bad when it rained. The PO had drilled holes in the cowl under the hood on the drivers side to mount something. The srcrews went through the very bottom of the opening under the cowl, where the raised top of the vents come up through into the opening that is meant to keep the water from running down the vents. The screws went through to the inside of the firewall.

Its kind of hard to explain, and the screws did not need to be that long.
