I'm working on an 86 c10 and I've noticed when it rains, water in coming in behind the firewall and running down on to the floor boards inside.
I replaced the gasket under the hood and patched up a few large wholes that where on top between the wiper cowl and hood, but it's still coming in. I have new stuff to put on the floor, but i.dont want to install it till I stop the water. Any ideas or suggestions?
Thanks John

Big John, Try pouring water directly into the wiper cowl grill. It should run off to the sides and down behind the fenders. If it is the source, remove the wipers and cowl and go from there. While the cowl is off, make sure there is no leaves and debris stopping it from draining. The second area to check would be the windshield gasket at the top and bottom. If water is getting in at the roof line it can follow the channel and drain down behind the dashboard. If it is the glass side of the bottom of the gasket, it can do the same thing. The biggest problem with water is that it can travel many feet from where it started before it shows  up inside. I have owned a few older (60's and 70's) Chevy truck with the same issue. Sometimes it is a crack in the cowl near the wiper arms. Good luck

bigjohn,  I had the same problem with my 1994 Chevy W/T 1500 or (Work Truck).  It turned out to be leaking at the top of the windshield.  Since it was an old work truck I took the trim off and ran a nice bead all along the top then replaced the trim and it solved the problem.  To figure out the problem I used a garden hose and just ran water over the the truck to find the problem.  I also cleaned out the debris under the wiper cowl and it helped.  If you live with a lot of trees where you truck is parked it is more than likely clogging up the inside of the cowl.   Good luck.

Take care!

The worst water leak problems I've ever seen were in a 1970s Dodge Dart my mom had. Basically it would fill the entire glove compartment full of water in no time.

I'm going thru the same problem with mu 71 El Camino, not fun as this is my dd. I tracked it to the cowl area where I patched all the rust I could reach then tried to coat it with bed liner. well I got it down to a drip and not a run. 
If you buy a car from someone and they say it has no leaks RUN AWAY as fast as you can!!!!!!!

Rain today, Wet again!

If Stacey would like to do a show on finding and fixing water leaks in a classic car I have one he can use! I'm at wits end, when I think I have it almost fixed it hits me in the face again...
