What It Helps Fix

• Oil vapor seepage from deteriorated hose material
• Improper hose routing or poor sealing at push-in connections
• Emission system faults related to damaged PCV-to-intake plumbing

Installation Notes and Tips

Verify the vehicle’s engine configuration, heated PCV valve setup, and hose routing before installation. Match the push-in ends to the original connection points and confirm the molded branch orientation aligns with the factory layout. Inspect adjoining PCV components and intake fittings for wear, carbon buildup, or damage before installing the new hose.
