The distributor/oil pump housing also contains the oil pressure relief valve.  The outermost piece of the pressure relief valve is a piston like piece with an o ring on it and held in place by a roll pin.  I would guess that o ring is leaking.  I am trying to determine if it is possible to remove the pressure relief valve with the housing still attached to the engine.  I haven't had a chance to really get into it yet.  There is a very good YouTube video regarding the oil pressure relief vale @
