An oil separator for separating and collecting lubrication oil contained in blow-by gas of an internal combustion engine. The separator is formed in the cylinder-head cover of the engine and incorporates a porous filter or filters made of foam metal for absorbing oil constituents in the blow-by gas. The filter is vertically arranged so as to make the absorbed oil to fall to the bottom of the separator and to be collected by the oil reservoir for recycling the separated oil to the cylinder.
