Earl's Performance 3434122ERL Oil Fill Cap with PCV Vent ORB Port - and 10

The Earl's Performance 3434122ERL oil fill cap is engineered to simplify catch can and PCV system installation on late-model engines without requiring valve cover modifications. This billet aluminum cap threads directly into your valve cover like a standard oil filler cap while providing a dedicated -10 ORB (7/8"-14 straight thread O-ring) port for plumbing to a catch tank or PCV system.

Key Features:

• Integrated baffle and -10 ORB port for clean, professional catch can installation
• Eliminates the need to drill or modify valve covers for racing applications
• Billet aluminum construction with durable black anodized finish
• Compatible with OEM valve covers on GM LS, GM Gen-V LT, and Ford Coyote engines
• Direct thread-in replacement for factory oil fill caps
• Meets sanctioning body requirements for catch can systems in racing applications

This cap is designed for use with Earl's ORB (O-ring port) hose ends such as AT849010ERL, or O-ring port to AN flare adapters AT985010ERL (straight) or AT949010ERL (90-degree), allowing you to route AN hose directly to your catch tank. Note that this version fits OEM valve covers; a separate version is available for Holley cast aluminum GM LS valve covers.
