Description

Oil Separator Drain Hose for the 300 Tdi 2.5L 4-cylinder turbo diesel engine, part of the crankcase ventilation system.

It returns the oil collected by the oil separator back to the crankcase, draining condensed oil from the separator housing so that crankcase blow-by vapour is vented while the separated oil is retained in the engine. A clear, correctly routed drain hose prevents oil build-up in the separator and keeps the breather circuit working as intended.
