Detailed Product Information

This Dorman PCV valve tubing is built to replace the original equipment hose used in crankcase ventilation systems where a secure, leak-free connection is important. By restoring proper routing between PCV components, Dorman 46014 helps maintain stable engine ventilation on applications such as the Buick Century, Chevrolet Lumina, and Pontiac Grand Prix. This part cross-references GM OE 24506734 for the same application.

The Dorman 46014 part number is also a useful reference when matching the correct hose configuration for service work on these vehicles.

What It Helps Address

• Cracked or brittle PCV hose material
• Vacuum leaks caused by a deteriorated ventilation tube

Installation Notes and Tips

Verify the hose shape, connector count, and inside diameter before installation. This part uses a push-on attachment method, so clean the mating ports and inspect nearby PCV components for wear before fitting the new tubing. Confirm vehicle-specific routing on the Buick Century, Chevrolet Lumina, Pontiac Grand Prix, and other listed models before final assembly.
