Screen Assembly

The Screen Assembly (MPN 241S) is a press-on oil pump pickup screen designed specifically for big block Chevy engines running stock oil pans. As a mechanic working on classic and high-performance builds, you know that proper oil flow from the pan to the pump is non-negotiable—any restriction or contamination in this critical passage can starve your engine of lubrication, leading to bearing wear and catastrophic failure. This screen assembly serves as your first line of defense, filtering debris while maintaining the flow rate your engine demands during idle, cruise, and full throttle operation.

Engineered as a press-on design, the Screen Assembly installs directly onto the oil pump pickup tube without requiring welding or additional fasteners, making it ideal for both original restoration and modern rebuild scenarios. The mesh screen material is sized to trap ferrous particles, bearing debris, and sludge while allowing unrestricted oil passage under all load conditions. The compact footprint (5.5 × 2.7 × 5.7 inches) and lightweight construction (0.46 lbs) ensure no interference with pan geometry or engine bay clearance, critical considerations when working within the tight constraints of big block installations where oil pan access is already limited.

This assembly benefits builders and restorers of big block Chevy engines—whether you're sourcing a complete stock rebuild or upgrading a vintage race platform. Installation involves pressing the screen onto the existing pickup tube; no modification to your factory oil pan is required. Mechanics appreciate the reliability of this proven design, especially when diagnosing oil delivery issues or performing preventive maintenance on engines with unknown service history. For anyone committed to protecting their big block investment with quality filtration at the source, this screen assembly is an essential component.
