For those who have water leaking from dash...
Yep. If you find him let me know. I would like to kick him in the junk too.
How many times I have thought that.
I've been slowly tracking down my leaks and am
almost confident that it is dry. I started with the obvious windshield gasket. Did that twice due to not using liquid (tube) butyl in the lower edge. The wiper pivots also took 2 tries. The second time was to add grease fittings. If they are not really tight you can get a drip through them. The purple gasket (which should be black) does nothing for keeping your feet dry. That is more of a positioning device to keep the wiper centered. The white foam will crush to a paper thin membrane and I am not even sure that it needs to be there. I got my seals from DMT and they came with a rope caulk to put around the base. That is what really seals it. The second time I put them back it I used some rope caulk from my windshield install.
Other leaks. Don't assume that that is all your leaks. The cowl itself could be leaking. And, the edges of it are not very wide flanges and are just overlapped with sealer between. The first place I found was a couple pinholes in the low point by the air inlet to the heater box, near the right cowl drain. Then I found a hole in lower right corner of windshield by A pillar that I missed.
Last but not least is the one pictured below. On the drivers side - the top of inner side panel has a small flange that comes up under the cowl drain. I don't have carpet in yet, so every time we got heavy rain I saw a little water pooled in 2 ribs of the floor. I found it by dusting the inside with flour and was able to see a trail to the source next time it ran in. It was partially rusted away and even though I had seam sealed it from the inside water was still getting through. You would never see this unless you looked up from under it with the fender off. I found that Black Jack neoprene roof caulk does a much better job on these areas than seam seal.
