Looking for the Group's Collective Opinion ...

I've got a Wheel Horse 1067 with a Kohler 10hp engine.  The engine runs fine.   Starts right up,  No smoke.  Doesn't burn oil.  The problem I have is that there is always a "wet" film of oil just below what I believe is the fuel pump.  It never drips, but seems to seep out very very slowly.  I probably lose an ounce of oil a year.  My questions are ... what is the likely source of the seepage; am I asking for trouble if I don't correct it;  what is the likely solution; and how difficult is this?  I have attached some pictures to give a better idea of what I'm talking about.  Appreciate your thoughts ...

  Have you replaced the gasket for the fuel pump, or the cam gear gasket?

Could also be a little oil misting out of the breather. An ounce a year, I'd leave it alone. Just clean the area every so often.

I've never done any work on the engine.  This was my dad's tractor.  I believe everything is still original.  It is why I'm reluctant to try to fix something that may not be broken - worried I might open a can of worms.  On the other hand, I don't want to overlook something that might be having more serious consequences I'm not aware of.  The engine side of things is new to me, other than oil, filters, belts, etc.

My 855 started doing that a few years ago, i think mine is from the breather.  Such a small amount its hard to tell, so i leave it alone

There was a change to the crankcase breather for the K-181's and M8's.

That's a Orginal fuel pump with the cast housing. When they get some wear the pivot pin for the pump lever will sometimes start a very slow leak as you have described.
