Perkins Prima M50 oil leak

I have a friend here at anchor in Prickly Bay, Grenada with a Perkins Prima M50 circa 1989.
His engine breather system is leaking a bit of oil (1/2 liter in 24 hours) at the diaphragm unit. He has changed the unit but this has changed nothing.
From what I can see, this is a crank case breather system, but being completely unfamiliar with this particular engine, I'm only guessing.
I believe that his rings may be going, putting more than normal pressure in the crank case, creating the problem, but I'd rather not give him this bad news w/o some confirmation.
Anyone with knowledge of this particular engine who has any input, please help me help my friend.
Thank you.
