Detailed Description

This PCV valve grommet is engineered as a direct-fit replacement for the original grommet used on select 1986-1989 Chevrolet S10, Chevrolet S10 Blazer, GMC S15, and GMC S15 Jimmy models. The rubber material helps maintain a secure seal where the PCV valve or crankcase vent tube passes through the valve cover or related mounting point. Dorman 47048 is a practical replacement when the original grommet has hardened, cracked, or no longer holds the vent tube securely. This part cross-references OE number 14091871 for the same application.

What It Helps Fix

• Cracked or brittle PCV valve grommet material
• Loose fit at the crankcase vent tube opening
• Air leaks caused by a worn sealing grommet
• Oil vapor seepage around the PCV valve mounting point
• Improper retention of the vent tube on left-side applications
