PCV Valve

The Subaru PCV Valve, also known as a Valve Complete Control, is an essential emissions component that regulates the flow of crankcase gases. Replacing a faulty valve can resolve common symptoms such as rough or high engine idle speeds, unexplained exhaust smoke, or pressure issues that cause the dipstick to lift or the oil fill cap to exhibit hissing sounds while the engine is running. This genuine part (11810AA131) directly supersedes previous part number 11810AA130. Note that this component is production-date sensitive for certain engines; for instance, some service records indicate a transition between versions around mid-2015. Crucially, this part does not fit the 2021 Subaru Outback 2.5L CVT Limited. Please verify your specific vehicle's production date and engine configuration to ensure compatibility before installation.
