Help Diagnose Oil leak in Onan BGE 5000 RV Genset

My Onan 5000 is leaking oil. Its 20 years old. I loosened all the screws on the cover but i cannot get it off to see behind.
  • Its leaking sputtering our on the left side away from the plug. Behind a U shaped cover which i was trying to remove so i could see. I assume there will be a crankcase behind it that might have a bad breeather and gasket. Not sure of course. Ill get picture.
  • So it is an 2002 MH, but we do not have enough information on what you removed the screws from. A picture would be helpful. Are you sure the oil fill plug is in tight?
