PROBLEM TO BE SOLVED: To provide an oil separator for assistingly forcing oil through a narrow wave-shaped passage into an oil drain. SOLUTION: An oil separating device is provided for separating micron and sub-micron particles of oil from crankcase gases. The device includes a housing having a first chamber 14 in communication with and a second chamber, and the narrow wave-shaped passage 24 disposed between the first chamber and the second chamber 16. The narrow wave-shaped passage 24 is defined by a first inner wall having a first undulating surface opposite and spaced apart from a second inner wall having a second undulating surface mirroring the first undulating surface. The narrow wave-shaped passage is disposed downstream of the first chamber and above the oil drain so as to allow oil particles in crankcase gases passing from the inlet to the outlet to accumulate on the first and second inner walls and assists gravity in forcing the accumulated oil through the narrow wave-shaped passage into the oil drain.
