What It Helps Address

  • Cracked or brittle crankcase breather hose material

  • Oil vapor routing issues caused by hose deterioration
  • Improper crankcase ventilation flow from a damaged hose

Installation Notes and Tips

Verify the OE number and vehicle application before installation. Confirm hose routing, connection points, and available clearance against the removed part to ensure the replacement matches the original layout. For best results, inspect adjoining crankcase ventilation components for wear, oil saturation, or cracking before reassembly.
