Product Details

Dorman 46079 is a replacement PCV hose made for the crankcase ventilation system. It replaces an original hose that has become hard, split, or leaking, which can affect airflow through the PCV system and contribute to rough running conditions. This hose is sized with a 0.57-inch inside diameter and is made from nylon to better withstand age-related deterioration. For buyers searching for a 2003 Lincoln Aviator PCV hose, a 2004 Lincoln Aviator crankcase ventilation hose, or a 2005 Lincoln Aviator PCV valve hose, this part matches the listed application.

This part cross-references Ford OE part number 2C5Z6A664A for the same application.

Common Issues It Can Address

  • Cracked or brittle PCV hose material
  • Vacuum leaks in the crankcase ventilation circuit
  • Oil vapor seepage from a deteriorated hose
  • Unstable idle caused by damaged ventilation plumbing
  • Loss of proper crankcase airflow on Lincoln Aviator models

Installation Notes

Verify hose routing and connection points before installation. Inspect adjoining PCV components, fittings, and nearby vacuum lines for wear or contamination so the replacement hose is not installed into a damaged system. Confirm the 0.57-inch inside diameter matches the vehicle connection points before final assembly.

Quality Assurance

Dorman replacement parts are engineered to match the original application and use materials selected to withstand common failure modes such as cracking and brittleness. Part number 46079 is listed for 2003-2005 Lincoln Aviator applications.
