Detailed Description

Standard Ignition V323 is a replacement PCV valve designed for Toyota crankcase ventilation systems. It is listed for 1994-1998 Toyota T100, 1995-1999 Toyota Tacoma, 1996-1999 Toyota 4Runner, and 1997 Toyota Previa, with 2000 Toyota 4Runner fitment for vehicles equipped with California emissions. This part number, V323, is also referenced by 2-9521, 1220475010, and PCV521 for the same application.

As a PCV valve, this component helps regulate crankcase vapors through the emission control system and maintains the hose routing specified by the vehicle application. The straight, push-on design and compact plastic body support a clean replacement on the listed Toyota models.

What It Is Used For

• Replacing a worn or sticking PCV valve on Toyota 4Runner, Tacoma, T100, or Previa
• Restoring crankcase ventilation flow in the emission control system
• Addressing rough idle caused by PCV valve restriction or leakage
• Correcting oil vapor buildup in the crankcase ventilation circuit
• Servicing a cracked or deteriorated valve body in the hose path

Installation Notes and Tips

Verify hose diameter and valve orientation before installation. Standard Ignition V323 uses a push-on attachment with straight nipple routing, so the existing hoses should seat securely on the inlet and outlet ends. Confirm the vehicle’s emissions configuration, especially on the 2000 Toyota 4Runner, which is listed for California emissions applications.

Quality Assurance

Standard Ignition supplies replacement ignition and emission control components for service applications. V323 is built as a dedicated PCV valve replacement for the listed Toyota fitments and cross-references common OE and aftermarket part numbers for application matching.
