Genuine Rocker Cover Breather PCV Valve - Nissan Patrol GU TD42T & TD42TI This Positive Crankcase Ventilation (PCV) valve is located in the rocker cover of your TD42T or TD42TI engine. Its job is to vent excess pressure from the crankcase, preventing pressure from building up and blowing out critical engine seals. When this valve becomes blocked with oil sludge, it can no longer function correctly. A blocked valve will lead to excessive crankcase pressure, which can force oil out of your engine's weakest points, commonly the rear main seal, resulting in costly oil leaks and potential engine damage. Features & Benefits Direct-fit Replacement: This is a quality genuine part that ensures a secure fitment and correct operation without any modifications. Prevents Oil Leaks: A functioning PCV valve properly manages crankcase pressure, protecting your engine seals from damage and preventing messy, expensive leaks. Restores Engine Efficiency: Ensures the crankcase ventilation system works as intended, contributing to a smoother running and more efficient engine. Engine Protection: By preventing pressure build-up and subsequent oil starvation from leaks, this small part plays a big role in the long-term health of your engine.
