I have a Sullair 185 Rotary Screw Air Compressor with a John Deer 4 cy diesel engine. The unit was make in the mid 80s. The engine oil started overflowing while the unit was operating. The engine oil does not appear to be diluted like it would be if fuel was getting into crankcase. The air compressor oil volume also does not appear to be going down. Does anyone know where this excessive oil could be coming from?
