[QUOTE="bigdogYJ, post: 20988, member: 11207"] A break in the rain today means I get to figure out where the water leak is coming from… So I pulled the cowling cover off, aside from being extremely dirty which I cleaned up as best I could, the cover over the air inlet seems to be intact. I’ve seen others that were just a plastic cover clipped in place with a seal or gasket. Mine seems to be a metal cover that’s sealed with some kind of lap sealant and the integrity seal seems to be pretty good. The black drip seems to be the primer from when the windshield was last replaced ~15 years ago. [ATTACH type="full"]1877[/ATTACH] I cleaned up everything I could inside and outside of the cowl poured some water down inside the cowl opening didn’t get any water inside port a lot more still didn’t get any water inside. started pouring from the top of the cowl still didn’t get any water inside. Worked my way up the a pillar took the garnish off the side of the windshield Cleaned that up as best I could. Poured water down the a pillar still no water inside. Poured water from the top of the windshield on the passenger side let it run all the way to the edge all the way down the windshield to the cowl etc. still no water inside. Finally ended up pouring water above the top of the windshield on the driver side about over the steering wheel, instantly water started pouring inside. Bingo! [ATTACH type="full"]1878[/ATTACH] It was a pretty significant leak. The whole passenger door sill channel was filled and the carpet was soaking it up along that whole side. [ATTACH type="full"]1879[/ATTACH] Basically the water would drip behind the seal above the windshield on the driver side run across the top side of the headliner board to the passenger a pillar run behind the passenger a pillar trim down to the dashboard dripped down behind the dashboard and would basically drip into The blower motor area and it would drip out of there onto the floor and then down into the door sill. Not sure if just good ole silicone bead across the top is worth trying, or start with a piece of clear tape across the whole top for now, or just get it done right and have it all resealed.
