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?
