Description

Breather and oil filler cap for the rocker cover, part of the engine crankcase ventilation system on the 2.25L and 2.5L 4-cylinder petrol and naturally aspirated diesel engines.

Mounted on top of the rocker cover, the unit vents crankcase pressure through an integral wire-mesh breather filter while also serving as the oil filler point. Relieving crankcase pressure protects the gaskets and oil seals from being forced out under engine blow-by.
