M25 / XP gear cover oil leak (possibly?)

[KWKloeber]

Has anyone with an M25 or XP experienced an oil lesk that gets slunged all over and coats the cover, coolant hose, and whatnot else?

(this is another owner's issue)
He hasn't yet been able to narrow down the source.

This is < 5 min running after completely cleaning the cover bone dry:

Ken : I don't understand "gear cover"???  Valve cover?

Well crap the pic didn't post.

Kubota calls it a gear case.  Conventionally motor heads would call it a timing cover (so does Wb), but there's no timing belt under there so that terminology isn't really correct.  I go with Kubota parts terminology.
eg, front of the engine.
