Bb Lifter Val. Oil Baffl

The MOROSO Lifter Valley Oil Baffle (MOR25100) is a precision-engineered aluminum component designed for Big Block Chevy engine applications. This valley oil baffle serves a critical function in managing oil circulation and preventing overflow in high-performance or heavily modified engine configurations where factory baffles prove inadequate. Available in natural aluminum finish, this OEM-quality part addresses a common point of failure in aggressive engine builds.

Constructed from aluminum, the baffle weighs 2.35 lbs and measures 6.3 x 2.3 x 21.8 inches, allowing direct fitment into factory mounting locations. The valley baffle controls oil splash and pooling in the lifter valley, preventing pressure loss and contamination during extended operation or sustained high RPM running. MOROSO's engineering ensures proper clearance around pushrods and rocker arms while maximizing baffle surface area for effective oil management. This is a direct replacement component, not an aftermarket enhancement—precision fit is essential.

Engine builders and Big Block Chevy enthusiasts install this baffle when rebuilding for street performance, track duty, or marine applications where oil system integrity directly impacts reliability. Oil starvation at the cam bearings and lifters is a recognized failure mode in modified BBC engines; a quality valley baffle mitigates this risk by maintaining consistent oil level in the lifter gallery. Whether you're freshening a 396, 427, or 454 BBC, a proper valley baffle is non-negotiable for long-term durability. This MOROSO piece is OEM-equivalent in quality and fitment.
