[DML] Re: Valley of death - no more

["Dave Swingle" <swingle@xxxxxxxxxxx>]

Anything is better than letting it fill up with road dirt and old 
coolant though, so I'm sure this will help. I have also seen cars 
where the top of the engine has rotted through. 

I'm not a big fan of filling in the holes, my thought is that when 
the filler ultimatly breaks down it will hold moisture in there even 
moreso. My preference is to clean it up as best I can, including wire 
brushing and solvent, and then paint the valley from head-to-head 
with POR15. 

The cover deflector plate is a great idea! Did you happen to take any 
pictures of that?
