An oil separating device for separating micron and sub-micron particles of oil from crankcase gases is provided. The oil separating device includes a housing having a first chamber in communication with a second chamber, and a narrow wave-shaped passage disposed between the first chamber and the second chamber. The narrow wave-shaped passage 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 assist gravity in forcing the accumulated oil through the narrow wave-shaped passage into the oil drain.
