ABSTRACT:
An oil separator for separating and collecting lubrication oil contained in blow-by gas of an internal combustion engine. The separtor is formed in the cylinderhead cover of the engine and incorporates a porous filter, which is made of foam metal for absorbing oil constituents in the blow-by gas, and a relief valve which is arranged between a chamber of the downstream-side of the porous filter and the crank case in order to pass the blow-by gas therethrough into downstream-side from the crank case when the internal pressure of the crank case increases.
