The Genuine Subaru PCV Valve Pipe is an OEM replacement component designed to connect the PCV system to the engine's crankcase ventilation plumbing. It is manufactured to Subaru specifications for proper fitment and reliable crankcase ventilation.
The PCV valve pipe is part of the positive crankcase ventilation system. It provides the connection needed to route crankcase vapors through the PCV system, helping regulate crankcase pressure and return combustion byproducts to the engine's intake system for proper combustion.
A damaged, cracked, restricted, or deteriorated PCV pipe can contribute to vacuum leaks, improper crankcase ventilation, or oil vapor leaks.
