I don't know what that gunk is but there are seals inside the valve cover for each cylinder.

Hopefully there aren't any cracks. Might want to just replace the valve cover seals (1 big one, 4 small ones).

With that said, that does look suspiciously like coolant. Hopefully that isn't a failed head gasket.
