Detailed Description

Standard Ignition GV4 is a PCV valve grommet engineered for emission system repair where the original rubber grommet has hardened, cracked, or lost its seal. Standard Ignition applies manufacturing quality control throughout the process to help address common failure points in emission components. This part cross-references Dorman - HELP 42065 for the same application. The GV4 is listed for vehicles such as the Ford F-150, Ford Bronco, Ford Mustang, Mercury Capri, and Ford E-250 Econoline Club Wagon, making it a practical replacement for service work on older Ford and Mercury platforms.

What It Helps Fix

• Vacuum leaks at the PCV valve opening
• Cracked or brittle rubber grommets
• Loose PCV valve fitment in the valve cover or intake
• Unstable idle caused by air leaks in the emission system
• Oil vapor seepage around a worn PCV valve seal

Installation Notes and Tips

Verify the required opening size before installation; fitment notes list a 1/2 inch inner diameter for many applications. Inspect the PCV valve and surrounding hose connections at the same time, since a worn valve or damaged hose can affect sealing performance. Confirm vehicle year, make, and model against the fitment list before ordering.
