Detailed Description

Standard Ignition V261 is engineered as an OE-style PCV valve replacement for emission control systems that rely on controlled crankcase ventilation. Standard Ignition applies manufacturing quality control from component sourcing through finished product inspection, helping ensure consistent fit and function for the listed Buick, Oldsmobile, and Pontiac applications. This part cross-references AC Delco 25096931 and PCV146 for the same application.

Common Problems This Part Can Address

• Rough idle caused by a sticking or restricted PCV valve
• Excess crankcase pressure from poor ventilation flow
• Oil vapor buildup in the intake system
• Vacuum leaks related to a worn PCV valve connection
• Emission system faults tied to crankcase ventilation performance

Installation Notes and Tips

Verify hose size and connector layout before installation. The V261 uses two hose connections and no connector, so match the existing routing on the vehicle before replacing the valve. Inspect the hoses for cracks, soft spots, or oil saturation, and replace damaged hoses to maintain proper sealing and airflow. Confirm the part number against the vehicle’s engine and emission configuration for the listed model years.

Quality Assurance

Standard Ignition manufactures emission components with process control from raw componentry through final assembly. The V261 is produced to address common failure points found in original equipment PCV valves and to provide a consistent replacement for the specified GM applications.
