Detailed Product Overview

This Dorman PCV valve grommet, part number 42049, is engineered as an OE-style replacement for vehicles that use a valve cover-mounted or oil filler-mounted PCV connection. The rubber design helps maintain a secure seal around the PCV valve, supporting proper crankcase ventilation system operation on applications such as Ford Taurus, Ford F-150, Ford Mustang, and Mercury Sable. This part cross-references Standard Ignition GV27 for the same application.

What This Part Helps Address

• Cracked or hardened PCV grommet material
• Loose PCV valve retention at the valve cover
• Air leaks at the PCV valve opening
• Oil seepage around the grommet area
• Improper sealing after PCV service

Installation Notes and Tips

Install the grommet by pushing it into the designated opening, then seat the PCV valve fully into place. Verify the valve cover or oil filler opening is clean and free of old rubber residue before installation. Confirm the application notes for your vehicle, since some listed models use valve cover fitment while others use oil filler fitment.
