Timing Cover Seal Mopar V8 SB/BB

The Timing Cover Seal Mopar V8 SB/BB (SKU M7764573) is a critical OEM-specification replacement seal engineered for Mopar B-Series and RB-Series big-block and small-block V8 engines. This rubber timing cover seal prevents oil seepage at the front engine cover, a common leak point that—left unaddressed—can lead to oil starvation, bearing damage, and catastrophic engine failure. Whether you're restoring a classic Mopar muscle car, maintaining fleet vehicles, or performing routine preventive maintenance, this seal is essential for engine longevity and reliability.

Manufactured by MAHLE ORIGINAL/CLEVITE under MPN 64573, this timing cover seal is engineered from durable synthetic rubber formulated to withstand continuous exposure to engine oil, heat cycles, and mechanical stress without hardening or cracking. The seal's compound resists degradation from modern detergent oils and maintains its elasticity across the full operating temperature range of V8 engines, ensuring a consistent, pressure-tight fit against the timing cover. Precision molding guarantees exact dimensional conformity with the 4.3 x 0.9 x 6.55 inch profile required for proper seating and load distribution.

This seal is the direct replacement for any Mopar B-Series or RB-Series V8 requiring factory-spec timing cover gasket renewal. Installation requires no special tools beyond basic hand tools and a gasket scraper; the lightweight design (0.13 lbs) simplifies handling during engine work. Proper installation involves cleaning all old gasket residue, applying a thin bead of gasket sealant to the timing cover, and torquing fasteners to Mopar specifications to avoid over-compression, which can compromise seal integrity and cause recurrent leaks. OEM-equivalent quality ensures compatibility with original equipment and aftermarket performance builds.
