Genuine Honda PCV Valve 1.5 Turbo OEM 17130-59B-003 | Civic, CR-V, Accord

Genuine Honda PCV Valve (Crankcase Ventilation) OEM 17130-59B-003 – 1.5 Turbo

The PCV (Positive Crankcase Ventilation) valve is a crucial component of the engine's breathing system, specifically designed for modern **Honda 1.5L turbocharged engines (L15 series)**. Its primary role is to precisely control the flow of blow-by gases from the crankcase back into the intake manifold, preventing pressure buildup inside the engine block.

In direct-injection turbocharged engines, the efficiency of this valve directly impacts the cleanliness of the intake valves (reducing carbon buildup) and the longevity of all engine seals. Choosing a **Genuine Honda OEM** part ensures the correct internal spring calibration, which is vital for maintaining the delicate pressure balance that aftermarket alternatives often fail to replicate.

Applications

This valve is dedicated to 1.5 Turbo engines (engine codes: L15B7, L15BB, L15BE, L15BG, L15BJ) found in the following models:

• Honda Civic 4D / 5D: 2016–2021 (EU & USA models)
• Honda CR-V: 2017–2025 (EU & USA models)
• Honda Accord 4D: 2018–2025 (USA models)
• Honda HR-V: 2019–2020 (EU models)
• Honda ZR-V: 2023–2025 (USA models)

Why a Healthy PCV Valve is Critical for Turbo Engines

In a turbocharged engine, the PCV valve acts as a sophisticated one-way check valve. When the turbocharger creates boost pressure, the valve must close completely. If it leaks, boost pressure enters the crankcase, which can lead to:

• Blown crankshaft seals or the oil dipstick being pushed out,
• Sudden oil leaks (e.g., from the valve cover gasket),
• Rough idle and "Check Engine" lights due to air-fuel mixture issues,
• Accelerated "Oil Dilution" (gasoline mixing with engine oil).

Installation & Technical Tips

• Checking the valve: The most reliable way to test this valve is by checking its "check-valve" function. You should be able to blow air through it in one direction (towards the manifold), but it must provide absolute resistance when blowing from the opposite side.
• Rattle Test Note: Unlike older Honda models, a new 17130-59B-003 valve may not "rattle" when shaken. This is normal due to the precise internal spring tension of the modern design.
• Check the hoses: Always inspect the rubber PCV hose for softness, cracks, or swelling. Oil degrades rubber over time; if the hose feels spongy, replace it along with the valve.
• Service Interval: To help prevent carbon buildup on intake valves, we recommend a preventive replacement every 40,000 – 50,000 miles (approx. 60k-80k km).

FAQ – Frequently Asked Questions about 17130-59B-003

Can I clean my old valve with carb cleaner?
Cleaning is only a temporary fix. Harsh chemicals can damage the internal seals. In a Turbo engine, even a small internal leak under boost can cause major issues. A new OEM valve is the best insurance for your turbo and engine seals.

Will a new PCV valve fix my "Oil Dilution" problem?
A functioning PCV system is essential for evaporating fuel vapors from the oil pan. While it is not the only factor in the 1.5 Turbo oil dilution phenomenon, a healthy valve is a fundamental requirement for the ventilation system to work as intended.
