Detailed Description
Standard Ignition V478 is a replacement PCV valve for emission control and crankcase ventilation service. It is listed for 2005-2011 Volvo XC90 and 2007-2010 Volvo S80 applications, making it a focused choice for Volvo XC90 and Volvo S80 maintenance when the original valve is restricted, leaking, or no longer regulating crankcase flow correctly. This part cross-references 2-9620 and PCV445 for the same application.
What It Helps Address
- Excess crankcase pressure
- Oil vapor buildup in the ventilation system
- Rough idle caused by a faulty PCV valve
- Vacuum leaks related to worn valve connections
- Emission control issues tied to crankcase ventilation flow
Installation Notes and Tips
Verify hose size, inlet diameter, and outlet diameter before installation. The push-on design and angled nipple orientation should match the existing routing on the vehicle. Inspect the hose ends, O-ring sealing surface, and mounting point for wear or contamination before installing the new valve. Confirm fitment by model year before ordering for Volvo XC90 or Volvo S80 service.
Quality Assurance
Standard Ignition supplies replacement emission control components for service applications, and this V478 PCV valve is built with the listed OE-style attachment and sealing features for a proper replacement fit.
