Dorman PCV Valve Engine Oil Separator

The Dorman PCV valve engine oil separator (also called a PCV oil separator, crankcase ventilation oil separator or air-oil separator) is a replacement part for the positive crankcase ventilation system. It helps keep oil vapor and blow-by gases from the crankcase out of the intake. Dorman, a long-established aftermarket supplier, designs these parts as direct replacements for original components that wear out or fail over time.

Key Features:

• Separates oil mist from crankcase vapors so they can be routed back through the PCV system
• Helps maintain proper crankcase ventilation and reduce pressure buildup
• Helps address problems linked to a failed separator, such as oil consumption, rough idle, oil leaks and check engine lights
• Designed to replace the original part for fit and function
• Backed by Dorman's testing and quality standards

A working oil separator supports engine performance, helps control emissions, and protects intake components from oil contamination. Choose the child item that matches your application from the options on this page.
