This is a genuine Nissan Positive Crankcase Ventilation (PCV) valve, designed specifically for the Nissan Navara D40 and Pathfinder R51 models equipped with the VQ40 engine. Located on the driver's side rocker cover, this critical one-way valve vents crankcase gases back into the intake manifold to be safely re-burned. This process is essential for controlling emissions and preventing harmful pressure build-up within the engine.

Over time, the original PCV valve can become blocked with oil residue and carbon deposits, hindering its ability to function correctly. A clogged valve can lead to poor performance, increased oil consumption, and potential oil leaks from engine seals. Replacing a faulty PCV valve is a crucial maintenance task to ensure the long-term health and efficiency of your VQ40 engine.

Installation Notes

Installation is a straightforward task for a confident DIY mechanic and requires basic hand tools for access to the top of the engine. While replacing the valve, it is strongly recommended to inspect the connecting PCV hose and grommet for any signs of cracking, perishing, or oil-soaking. These components should be replaced if they are no longer providing a perfect seal.
