I have to park my Eagle in my driveway, under a tree, and I'm getting real tired of plucking leaf fragments out of the cowl vents. They get trapped between the slits in the sheet metal and the 1/4 inch wire mesh right below it, and can't be blown or sucked out. I have to get a tool and pulverize them, then try to vacuum them out before they fall into the cowl cavity. When I had to remove my wiper motor recently (as part of the valve cover replacement ritual), I discovered that the cavity where the wiper motor crank operates the wipers was also filled with debris.
So... I was thinking of making a simple cover out of sheet aluminum to fit over the vents and block them. I would also remove the windshield washer jets from their current position (below the cowl vents and firing up through a hole in the wire mesh) and mount them to (or inside) the block-out plate.
Has anyone else done this? Does anyone see any bad consequences of this mod? As far as I can tell, the only purpose of the cowl vents is do provide a drainage path for water coming down the windshield, and I'm not worried about that.
