Genuine Nissan Rocker Cover Breather PCV Valve TD42 - Nissan Patrol GQ GU This is the Positive Crankcase Ventilation (PCV) valve, located in the rocker cover of your TD42 engine. Its job is to manage crankcase pressure by venting excess gases back into the intake system to be burned. When this valve becomes blocked with oil sludge and carbon, pressure builds up inside the engine. If left unchecked, this pressure will find the weakest point to escape, often blowing out critical oil seals like the front or rear main seals, leading to major oil leaks and costly repairs. Features & Benefits Genuine Nissan Quality: Ensures you get a part that meets Nissan's exact specifications for performance and service life. Direct-fit Replacement: This valve is a direct-fit for the original, which ensures a simple and secure fitment with no modifications required. Correct Pressure Regulation: Restores the engine's ability to correctly vent crankcase pressure, protecting seals and gaskets from damage. Prevents Oil Leaks: By replacing a blocked valve, you prevent the pressure build-up that forces oil out of engine seals, keeping your engine bay and driveway clean.
