Oil Leak in Sport Jet 90

[Grasshopper187]

My 1993 Sea Rayder Sport Jet 90 is back together and running like a champ except for a small oil leak, about 2 oz/hr around the oil injector on the side of the powerhead. The powerhead was completely clean and dry before the test run. I checked the inlet and outlet hoses and connections and they're dry and tight but the side of the powerhead below the injector is wet (see photos). The rest of the powerhead is dry. Any idea where the oil is coming from?
