Product Description
EARL’S -10 ORB Oil Fill Cap with PCV Vent - Fits Holley Cast Aluminum Valve Covers
The Earl's Oil Fill Cap with PCV Vent is designed as a direct screw-in replacement for Holley cast aluminum valve covers, installing just like a standard oil fill cap. It features an internal baffle and a -10 ORB (7/8"-14 straight-thread O-ring port) for use with AN O-ring fittings and hose routing to a catch can or PCV system.
The design eliminates the need to modify or weld valve covers when adding a catch tank, making it ideal for racing applications where a vented oil fill or catch can is required by many sanctioning bodies.
This listing is for the version that fits Holley LS cast aluminum valve covers.
(A separate version is available for factory GM LS / LT valve covers part # 3434122ERL)
