Genuine Honda 17130-RCA-A02 PCV valve assembly for Honda outboards provides the OEM venting and crankcase pressure control required for reliable engine operation.

This Honda-branded PCV (positive crankcase ventilation) valve assembly is an original equipment manufacturer component designed to restore correct crankcase ventilation on compatible Honda engines. Using the sanctioned assembly helps maintain the original airflow routing, seal integrity, and durability engineered for Honda marine applications. Whether you’re repairing routine wear or returning a serviceable engine to factory specification, this part is intended to match Honda tolerances and installation points.

What does this PCV valve assembly do for my outboard engine?

The PCV valve assembly controls the flow of blow-by gases from the crankcase to the intake system, helping manage internal pressure and reduce oil carryover. It supports consistent combustion conditions and helps keep ventilation paths clear when functioning correctly.

• Regulates crankcase pressure during varying engine loads
• Guides blow-by gases back to intake or designated venting points
• Helps minimize oil vapor entering the intake
• Maintains OEM routing and sealing to prevent leaks

How do I know when this part needs replacing?

Replace the PCV assembly if you observe oil seepage, rough idling, excessive smoke, or visible cracks and wear on the valve or housing. Routine inspection during service intervals can reveal hardened hoses, torn seals, or stuck valve stems that indicate replacement is appropriate.

• Visible oil leakage or wetness around the valve housing
• Noticeable changes in idle quality or combustion consistency
• Cracked, brittle, or split hoses and gaskets
• Valve sticking — fails to open or close with engine vacuum

How do I install the Honda 17130-RCA-A02 PCV assembly?

Installation follows manufacturer guidelines: remove the old assembly, inspect mating surfaces, and secure the new OEM unit with the correct fasteners and hoses. Tighten fittings to specified torque and confirm hose clamps and seals are seated to prevent vacuum or oil leaks.

• Remove engine covers and access the crankcase vent plumbing
• Disconnect hoses, electrical connectors, and mounting hardware
• Install the new assembly, replace any worn hoses/clamps, torque fasteners
• Run engine and check for leaks and proper idle before reassembly
