Application Details

Built for vehicles that use a press-in PCV valve grommet, this Standard Ignition GV5 helps restore the connection between the PCV valve and the valve cover or intake opening. Standard Ignition applies manufacturing quality control from component production through finished part inspection, and the design reflects the brand’s focus on correcting common OE failure points in emission components. This part cross-references Dorman - HELP 42055 for the same application.

Compatible With many 1969-1991 Buick, Chevrolet, GMC, Oldsmobile, and Pontiac models, including Buick Regal, Chevrolet Camaro, and Pontiac Grand Prix platforms. Search terms such as PCV valve grommet for 1980s Chevrolet C10, rubber PCV grommet for Pontiac LeMans, or replacement grommet for Buick Skylark emission repair all point to this style of service part.

What It Helps Fix

• Cracked or hardened PCV grommet material
• Loose PCV valve fitment at the valve cover opening
• Vacuum leaks around the PCV connection
• Oil vapor seepage from a deteriorated seal
• Emission system service issues caused by worn rubber hardware

Installation Notes and Tips

Inspect the valve cover or intake opening before installation and clean away old rubber residue, oil, and debris. Verify the inlet and outlet diameters match the PCV valve and mounting opening before pressing the grommet into place. For best results, replace a hardened or damaged PCV valve at the same time if wear is present.

Quality Assurance

Standard Ignition manufactures emission components with process control from raw componentry to finished product. GV5 is produced as a replacement emission hardware part for consistent fit and sealing performance in service applications.
