Need advice on a rain leak
So I started to pull my interior out and under the factory insulation on the front passenger floor was a good amount of rust. The rubber/foam insulation by the firewall was wet as well. The car does not run (for 6 months now) so this is not coolant. Everything is on the car (hood, doors, seal etc) so no obvious leaks. Also the drain elbow is present on the firewall.
There are a few threads with good info on this but I just hosed the car down for 20 minutes especially around the cowl, passenger door, windshield etc and no water in the car. The carpet, seats and lower dash are out so I thought it would be easy to find the leak.
I would put everything back thinking it was just the heater core but that rubber foam was wet so there is some type of moisture getting in the car. Before leak testing I cleaned the cowl and door seals. I'm thinking maybe water was building up on the cowl and finding it's way in but I just want to make sure.
So for you guys who had leaks before, when you hose the car down does a good amount of water come in or is it a drip if water is reaching the right places? Also if I'm hosing down the cowl should water be coming out of the AC drain elbow on the firewall? (I'm a little unclear on that leak).
Thanks for any help.
