Abstract
In a venting arrangement for an internal combustion engine including a crankcase with a cylinder block, a cylinder head mounted on the cylinder block, a cylinder head cover mounted onto the cylinder head, and an oil separator integrally formed with the cylinder head cover, the oil droplets contained in the vent gases are separated from the vent gases as the vent gases are drawn through the oil separator and the oil-free vent gases are then supplied to the engine air intake duct. The oil is collected and drained by way of a siphon consisting of a cavity formed in the cylinder head and a drain pipe extending from the oil separator in the cylinder head cover into the cavity which, at its bottom, includes a bore through which a cylinder head bolt extends for mounting the cylinder head onto the cylinder block.
