Kubota 345 oil leak

[Rex eaves]

I read a post about a 345 oil leak that was determined to not be caused by a leaking head gasket. The person found the problem and solved it with epoxy. I seem to have the same problem. The leak is upper front of the engine. First thought was valve cover, 2nd thought head gasket, 3rd was timing gear cover.
I wondered where the person found the spot that solved the problem.
