2012 Toyota Venza - PCV Valve Hose Nipple
A positive crankcase ventilation (PCV) valve is designed to allow excessive pressure in the engine generated by crankcase gasses and oil vapors to vent to the intake and be burned. This limits excess emissions and prevents engine and gasket damage. The PCV valve hose nipple is the connection point of the PCV hose and may utilize a hose clamp to keep the hose tight and free from vacuum leaks.
