OK, so today I started the hunt for the mystery leak. When ever it rains or I wash my truck I have a small leak on the passenger side under the dash. Since I had the cowl off I thought it a good time to do some investigating. I learned quite alot about how the truck gets air from outside. This first picture shows the stack that air flows into, and keeps the rain (or wash water) out. You will notice there is a problem here!

Here's a look at the other side. Those are wholes there, yes!

I used a product from 'Locktite' I hope works as well as they say it does. It is called "Extends" and is a rust neutralizer. (I knocked off the big stuff first) This is a spray on product that is supposed to stop rust from continuing to form. After it dries you can paint over it and "Poof" no more rust! That's what they claim. We will see.
After it dried I used a product called "Dyna-Mat" to seal the wholes the rust made. Some of you might know this product as a noise dampening material used around speakers. I thought it looks like it will seal nicely. it is pliable and forms to what ever you stick it on. It also will not completely harden for a long time.

I applied a bit of black silicon to the edges just for fun.
Before I reinstalled the cowl, I noticed this little jewel. This is the wipe assembly support bracket.

It was painted rather poorly when they painted the truck. I sanded it down and repainted it flat black (no glare)
That's all I had time for today. Had to pay some attention to my wife. She lets me play with my truck, and I appreciate that so I try to give her some time back. Just a tip for you married guys out there.
Good luck with your leaks!
