Maintain correct crankcase ventilation and reduce engine blow-by emissions with this Genuine Nissan PCV Valve, designed specifically for Nissan Patrol GU models fitted with the TB48 engine. This OEM component regulates the flow of gases between the crankcase and intake system to help maintain optimal combustion efficiency, reduce oil contamination, and improve overall engine performance.

Over time, PCV valves can become clogged, stuck, or fail due to oil vapour buildup, carbon deposits, and prolonged use. A faulty or blocked PCV valve can lead to excessive crankcase pressure, increased oil consumption, rough idle, poor throttle response, smoky exhaust, and potential gasket leaks.

Manufactured to Nissan’s original specifications, this direct-fit replacement ensures proper ventilation, dependable operation, and long-lasting durability without the need for modification.
