The crankcase ventilation is maintained internally in the engine.

An oil separator is on top of the engine's camshaft cover. It separates the oil drops from the air in the crankcase. The drops are collected in a separator and flow back inside the engine to the oil pan. This prevents extra weight and space for external pipes.
