Abstract
Blow-by gas passages are formed on one side of the cylinder block and cylinder head of an internal combustion engine and spaced longitudinally of its crankshaft. The passages extend from the interior of the crankcase to a location above an upper face of the cylinder head, one of the passages being provided with a mounting port for an oil separator. The other blow-by passage is also connected to the separator, and the separator is connected to the intake system of the engine.
