Replace your worn or leaking PCV valve seal with this Genuine Nissan PCV Valve Grommet, designed specifically for Nissan Patrol GU Y61 models fitted with the TB48 engine. Located in the rocker cover, this grommet seals the Positive Crankcase Ventilation (PCV) valve to maintain proper crankcase pressure and prevent oil or vacuum leaks.

Over time, factory rubber grommets become hard, brittle, and cracked from constant heat exposure and oil contamination. A failing PCV grommet can lead to rough idling, vacuum leaks, oil seepage, increased emissions, and poor engine performance.

Manufactured to genuine Nissan OEM standards, this direct-fit replacement restores an airtight seal and reliable crankcase ventilation for long-lasting engine performance and reliability.

Why Replace Your PCV Valve Grommet?

A deteriorated PCV grommet may seem minor, but it can cause vacuum leaks, unstable idle, oil contamination around the rocker cover, and reduced engine efficiency. Replacing the grommet helps maintain proper PCV system function and protects your TB48 engine from unnecessary wear.
