Oil Separators for LS, Coyote, EcoBoost and Turbo Builds

What This Oil Separators Collection Covers

This collection covers application specific systems that manage oil vapor and blow by before it reaches the intake tract. Choose a kit that matches the engine PCV routing, boost level, space available and emissions requirements for the intended vehicle.

Catch Cans and Air Oil Separators

A catch can traps oil mist in a serviceable container. An air oil separator is often plumbed into the PCV circuit to separate oil while returning vapors through a closed system.

Selection tip

Use the item specifications and vehicle fitment filter to compare options for your exact application.

PCV Side and Crankcase Routing

Many applications use separate PCV and clean side connections. Follow the supplied hose routing and select a kit designed for the exact engine because port locations and vacuum sources vary.

Selection tip

Use the item specifications and vehicle fitment filter to compare options for your exact application.

Turbocharged and Direct Injection Engines

Boosted and direct injected engines can benefit from controlling oil vapor in the intake path. Select a closed system when the vehicle retains its factory PCV and emissions equipment.

Selection tip

Use the item specifications and vehicle fitment filter to compare options for your exact application.

Installation and Service

Mount the can away from exhaust heat, keep hoses free of kinks and empty the reservoir regularly. Cold weather condensation can increase service frequency.
