Key Features

• Part number GV16
• PCV valve grommet for emission control hardware service
• Rubber construction for a flexible sealing fit
• Direct replacement style for listed Buick, Chevrolet, GMC, Oldsmobile, Cadillac, and Pontiac applications
• Supports proper PCV valve retention at the mounting point

Detailed Description

Standard Ignition GV16 is engineered as an emission control hardware component for vehicles that use a PCV valve grommet in the crankcase ventilation system. The rubber material helps form a secure seal where the PCV valve seats, which is important for maintaining the integrity of the ventilation path and reducing leaks at the connection point. With fitment across many Buick Century, Buick LeSabre, and Pontiac Grand Prix applications, this grommet serves as a practical replacement for aging original parts.

Standard Ignition applies manufacturing quality control from component sourcing through finished product inspection, and the brand positions this part as a replacement for original equipment failure points. GV16 also cross-references Dorman - HELP 42056, making it easier to identify the correct PCV valve grommet for the same application.

What It Helps Address

• Cracked or brittle PCV valve grommet material
• Loose PCV valve fit at the valve cover or intake opening
• Vacuum leaks at the PCV valve mounting point
• Oil vapor seepage around a worn grommet
• Emission system service on older GM vehicles

Installation Notes and Tips

Verify the PCV valve opening size and application notes before installation. Some listed vehicles use a 7/16 inch inner diameter by 1 1/4 inch outer diameter specification, while others are noted for Federal or California emissions or shut-off delay configurations. Match the vehicle year, make, model, and emissions setup exactly to the fitment data for GV16.

Quality Assurance

Standard Ignition maintains quality control throughout the manufacturing process for emission components, from raw materials to finished part inspection. GV16 is built as a rubber replacement grommet for the listed applications and is backed by Standard Ignition’s emission-system manufacturing expertise.
