Genuine Honda PCV Valve Hose 1.5 Turbo OEM 17131-59B-010 | Civic CR-V HR-V

Genuine Honda PCV Breather Hose OEM 17131-59B-010 – 1.5 Turbo

This brand new, genuine Honda rubber hose connects the PCV valve to the intake manifold. It is a vital component of the crankcase ventilation system in modern **Honda 1.5L Turbo engines**. Engineered specifically for the high-heat environment of a turbocharged engine bay, this hose is designed to withstand constant exposure to oil vapors and fuel without degrading.

Choosing a **Genuine Honda OEM** part ensures a perfect fit with the correct pre-formed bends and length, preventing kinks that could restrict airflow. This hose is the official successor (latest revision) to the discontinued part number 17131-59B-000.

When to replace the PCV hose?

Over time, engine heat and oil chemistry cause rubber to lose its properties. Common signs that the hose needs replacement include:

• Hardening: The rubber becomes brittle, which can lead to cracks and vacuum leaks (unmetered air).
• Swelling: Oil exposure can make the rubber soft and "spongy," causing it to slip off the fittings.
• Oil Sweating: Visible oily residue on the surface of the hose or around the clamps.

Installation & Service Tips

• Replace with the PCV Valve: It is highly recommended to replace this hose whenever you install a new PCV valve (17130-59B-003 available HERE). An old hose may not provide a perfect seal on a new valve.
• Use Spring Clamps: Use original constant-tension spring clamps to ensure a secure seal regardless of engine temperature fluctuations.
• Clean Fittings: Ensure the mounting points on the manifold and PCV valve are clean and dry before sliding the new hose on.

FAQ – Frequently Asked Questions about 17131-59B-010

Can I replace this with a generic fuel hose sold by the meter?
It is not recommended. The OEM hose has specific pre-formed bends to fit the tight engine bay without kinking. A generic straight hose can easily collapse or fold, blocking engine ventilation and potentially causing blown seals due to overpressure.

Does this fit the Type-R (2.0 Turbo) model?
No, this hose is specifically for the 1.5 Turbo L15 engines. The 2.0 Turbo (K20C) engines utilize a completely different PCV layout and hose routing.
