Intake Gasket Set - Olds Big Block 1.500 x 2.575

The MAHLE ORIGINAL/CLEVITE Intake Gasket Set for Olds Big Block engines (1.500 x 2.575 rectangular port configuration) is a precision-engineered composite gasket assembly designed to seal the intake manifold-to-cylinder head interface on classic Oldsmobile V8 powerplants. This is OEM-specification replacement hardware for anyone maintaining or rebuilding big-block Olds engines where proper intake sealing is critical to prevent coolant and oil leakage into the combustion chamber.

The gasket set features composite construction at 0.06 inches thick, engineered to withstand the thermal cycling and pressure loads inherent to big-block operation. The 1.500 x 2.575 inch rectangular port dimension matches Oldsmobile's classic intake manifold specification, ensuring proper alignment and port-to-port sealing across all eight cylinders. MAHLE ORIGINAL/CLEVITE's manufacturing standards emphasize dimensional accuracy and material consistency—both essential factors in preventing intake manifold gasket failure, which commonly presents as coolant weeping at the gasket interface or cross-contamination between oil and coolant passages.

This gasket set addresses the needs of classic car builders, restoration enthusiasts, and engine shops performing top-end work on Oldsmobile V8 platforms. Whether you're rebuilding a 455, 425, or 400-cubic-inch big block, or simply replacing worn sealing surfaces during manifold removal, this composite set provides the OEM-equivalent sealing performance required to maintain engine integrity across temperature extremes and extended use cycles.

MAHLE ORIGINAL maintains a strong reputation for producing OEM-grade gasket assemblies that meet or exceed manufacturer specifications. For vintage American V8 applications where original equipment gaskets are difficult to source, MAHLE's modern engineering ensures reliable sealing performance without requiring substitution or engineering workarounds.
