Abstract

A blowby gas passage construction of an internal combustion engine is provided, wherein no outside pipeline is required for the engine, moisture included in the blowby gas may be prevented from freezing, and numbers of parts may be reduced so that the engine may be made into a compact type. In the internal portion of a cylinder head cover (1) mounted on a cylinder head, a blowby gas inside passage is formed so as to lead the blowby gas into the intake ports of the cylinder head. A rear end wall (1a) of the cylinder head cover (1) is provided on the surface thereof with a blowby gas introductory port (3a) that communicates with the blowby gas inside passage and a discharge port (2a) for discharging the blowby gas out of a positive crankcase ventilation (PCV) valve (2). Also, on the rear end wall (1a) is attached a rear cover (10) for covering the blowby gas introductory port (3a) and the discharge port (2a) and for making communication between both the ports (3a and 2a).
