Working

The Land Rover Genuine Crankcase Oil Breather 4585549 functions as a vital component of your engine’s ventilation system. It allows excess gases produced inside the crankcase to vent while separating oil vapours from these gases safely. The filtered gases are then either released or reintroduced into the intake system for controlled reburning, ensuring a balanced crankcase environment.

By managing internal pressure and minimizing vapour contamination, this breather helps preserve engine seals, prevent oil leaks, and improve both fuel efficiency and emission control, delivering smooth, reliable engine operation in all driving conditions.
