Holstein Positive Crankcase Ventilation PCV Valve

The Holstein Positive Crankcase Ventilation (PCV) valve line gives you OE-grade replacement PCV valves for domestic, European and Asian vehicles. The PCV valve is part of the crankcase ventilation system. It regulates and removes gases from the engine crankcase, which helps the engine run efficiently and keeps emissions down. Each valve in the line works as a one-way check valve. It meters crankcase vapors back into the intake so they can be burned off.

Key Features:

• Made as an aftermarket replacement built to match or exceed the original part
• Regulates crankcase ventilation to support engine efficiency and lower emissions
• Reinforced materials help protect against sludge build-up and oil leaks
• Units are tested for correct flow
• Premium O-rings and gaskets are used to help the valve last longer and seal reliably
• Covers a wide range of domestic and import applications

A worn or clogged PCV valve can cause rough idle, oil leaks and increased emissions. Replacing it with a Holstein PCV valve helps restore proper crankcase ventilation and keeps the engine running as designed.
