You can helicoil that bolt hole or if my memory is correct you can unbolt that part and install another one, or at least it did on the older EJ engines
Part Number: 13156AA052
What a mess, with the crap on the front of the cover, I'd say it's coming from higher up. Front main seal, probably.
Clean that thing off. You'll never pinpoint it with dirt and oil everywhere like that. Get a can or 2 of engine cleaner, grab a pair of ramps, and head to a coin-op car wash.
