Product Details

Gates EMH951 is part of the Gates Crankcase Vent Valve line, which focuses on direct-fit emission ventilation components. The product is engineered to match original equipment dimensions and function, helping maintain proper crankcase pressure control and ventilation routing. This part cross-references Standard Ignition V384 for the same application.

Use this valve on vehicles such as the 2003-2022 Honda Pilot, 2005-2025 Honda Odyssey, and 2014-2020 Acura MDX when replacing a worn or malfunctioning PCV valve. The Gates EMH951 also serves select Honda Ridgeline, Passport, Accord, Crosstour, and Acura TL, TLX, RDX, RLX, TSX, and RL applications.

Common Issues This Part Can Address

• Rough idle caused by restricted crankcase ventilation
• Excess crankcase pressure from a sticking PCV valve
• Oil vapor buildup in the emission ventilation system
• Check engine light concerns related to ventilation flow faults
• Reduced engine performance from improper crankcase pressure regulation

Installation Notes and Tips

Verify the original valve style and engine application before installation. Inspect the surrounding hoses, seals, and breather passages for buildup or damage, and clean the mounting area before installing the new valve. Confirm the valve seats fully and that the ventilation system routes correctly after service.

Quality Assurance

Gates states that its OE-exact crankcase ventilation regulators, PCV valves, and oil separators are built for exact fit and straightforward installation while restoring the emission ventilation system to proper operation and service life.
