Detailed Description

Standard Ignition V300 is a replacement PCV valve for 1993-1994 Nissan Maxima models. As part of the crankcase ventilation system, it regulates vapors routed from the engine crankcase back into the intake stream, helping maintain proper ventilation flow and system operation. The screw-in design, metal body, and straight nipple layout support a direct-fit style installation where the original service part uses a threaded valve.

This part cross-references PCV390 for the same application. If you are searching for a Nissan Maxima PCV valve, a 1993 Nissan Maxima PCV valve, or a 1994 Nissan Maxima PCV valve, V300 is the listed replacement reference.

What It Helps Address

• Crankcase ventilation flow restriction
• Oil vapor buildup in the engine crankcase
• Rough idle related to a worn PCV valve
• Excessive crankcase pressure
• Emission control service needs on the Nissan Maxima

Installation Notes and Tips

Verify the original valve uses a 3/8 NPT screw-in thread before installation. Inspect the hose connection point, surrounding vacuum lines, and sealing surfaces for wear or contamination before replacing the valve. Because gaskets are not included, reuse or replace any required sealing components separately based on the vehicle’s original setup. Confirm the valve orientation and hose routing match the existing Nissan Maxima configuration.

Quality Assurance

Standard Ignition supplies this PCV valve as a service replacement part for the specified Nissan Maxima fitment. The V300 is built with a metal housing and application-specific dimensions to match the listed crankcase ventilation service requirements.
