My first thought. Mine had leaves stuck in it and caused it to rust. I lucked out that it rusted the other way into the engine bay.

To get the cowl piece off you pull the wind shield wipers, and you'll find a few bolts holding the cowl on. After that is a plastic vent piece which also unbolts. Then you'll be able to see down in there. Clean out any gunk, and look for rust. Even if it turns out that isn't the problem, it doesn't hurt to clean it. Would have kept mine from having a new vent for the engine...
