Oil Pump/Front Cover 7-Bolt

The Oil Pump/Front Cover 7-Bolt (MPN: M198) is a critical engine component designed for vehicles requiring a seven-bolt fastening configuration. This assembly serves as the foundational element for your engine's lubrication system, housing the oil pump and protecting the timing chain or belt area. Whether you're rebuilding an engine, replacing a worn factory unit, or completing a full overhaul, this front cover assembly ensures proper oil delivery to all critical engine components and maintains vital sealing integrity.

Engineered with precision casting and machining, the Oil Pump/Front Cover 7-Bolt integrates the oil pump gears and drive mechanism directly into a single, compact housing. The seven-bolt design provides superior clamping force distribution across the front of the block, preventing oil leaks that commonly plague older or damaged factory covers. The cover's internal passages are precisely engineered to direct pressurized oil to the crankshaft, connecting rod journals, and camshaft bearings—the three critical wear points in any engine. Weighing 4.6 lbs and measuring 9.6 × 4.5 × 13.5 inches, this component balances durability with minimal added mass, making it ideal for both stock restorations and modified builds.

This oil pump and front cover assembly is essential for mechanics and engine builders working on specific platforms that use the seven-bolt configuration. Installation requires careful alignment of the pump driveshaft with the camshaft, along with proper torque sequencing of all seven fasteners to ensure uniform gasket seating. Before installation, verify your engine's compatibility with the M198 specification, as bolt count and gasket surface dimensions vary across model years and applications. Pairing this assembly with quality gaskets, fresh engine oil, and correct timing setup guarantees reliable oil pressure and engine longevity on first start-up and beyond.
