Subaru 11810AA000 Genuine PCV Valve — for Legacy, Outback, Impreza, Forester, SVX, Loyale & WRX

A smoking tailpipe, high or erratic idle speed, a dipstick that will not stay in its tube, or a hissing oil cap while the engine is running — these are common signs that your PCV system is failing . A stuck PCV valve can cause excessive crankcase pressure, forcing oil past seals and gaskets, leading to oil leaks and premature engine wear. Replacing it with this genuine Subaru part restores proper crankcase pressure and protects your engine.

This is a factory-original Subaru PCV valve (OE part number 11810AA000), designed for numerous Subaru models from the mid-1980s through the early 2000s. It is an Air Control Valve assembly engineered to regulate crankcase ventilation, maintaining optimal pressure and reducing emissions . This is the same part sold at Subaru dealerships.

When to Replace

• Excessive smoke from the tailpipe
• High or erratic engine idle speed
• The oil dipstick will not stay seated in its tube
• Hissing sound from the oil cap while the engine is running
• Visible oil leaks around engine seals and gaskets
• The valve does not rattle when shaken (stuck closed or open)

Product Details & Highlights

• ✔ Precision-machined valve — ensures accurate vacuum response
• ✔ Direct replacement — fits factory PCV hose and intake manifold
• ✔ Emission control — helps maintain proper crankcase ventilation
• ✔ Backed by Subaru’s manufacturer warranty (valid through any authorized dealer)
