Repleacement Rubber Seal SBC 2-Piece Timing Cover

The Replacement Rubber Seal SBC 2-Piece Timing Cover from CVR Performance (MPN TC23KT) is an OEM-equivalent seal kit engineered for small-block Chevy engines undergoing timing cover maintenance or restoration. Whether you're rebuilding a 350, 327, or another classic SBC variant, timing cover seals are critical components that prevent oil leakage at the front of the engine—a common failure point on both vintage and modified powerplants. This two-piece rubber seal design restores the compression fit between the timing cover and block, eliminating weeping that compromises engine cleanliness and oil level stability.

CVR Performance's timing cover seal utilizes durable elastomer construction formulated to resist heat cycling, oil saturation, and the thermal stress inherent in small-block Chevy applications. The two-piece configuration allows for straightforward installation without disturbing the entire timing cover assembly—a practical advantage when working on tight engine bays or performing mid-rebuild corrections. Unlike cork or felt seals prone to hardening and cracking, modern rubber compounds maintain flexibility across the operating temperature range of street and performance engines alike, ensuring a long-term leak-free seal.

This seal kit is ideal for engine builders, restorers, and weekend mechanics servicing small-block Chevy platforms in both stock and modified configurations. Installation requires only basic tools and takes minutes once the timing cover is removed, making it a smart preventative maintenance item during any timing cover work. The compact footprint (3.15 x 0.75 x 4.7 inches) and lightweight design (0.02 lbs) make handling and fitment seamless on any SBC engine. Verify your specific engine displacement and cover style before ordering to ensure compatibility with your build.
