How do you replace the PCV valve in a Nissan Murano?

To replace the PCV valve in a Nissan Murano, first locate the valve, which is typically found on the valve cover or near the intake manifold. Disconnect the hose attached to the PCV valve and remove the old valve by twisting it out of its socket. Before installing the new valve, ensure that the grommet is in good condition or replace it if necessary. Finally, insert the new PCV valve, reconnect the hose, and ensure everything is secure before starting the engine.
