I'm working on this issue currently I pulled the cowl and found a bunch of dirt and such.

Also the seal between the floor and the firewall is/was cracked and brittle i have taken all of that out and working on putting rust inhibitor, POR-15 and 3M sealant down. I'm not totally done but definatly sure this isn't helping the water flow out.

here is a link to my post with a few pics of what i found.
