Repl Cam Plate Seal

The Allstar Performance Replacement Cam Plate Seal (ALL 90089) is a precision-engineered rubber and steel camshaft seal designed to prevent oil leakage at the front of the engine block. Built for high-performance and street engines, this cam plate seal maintains a tight barrier between the camshaft and cylinder head, critical for preserving oil pressure and preventing contamination of the engine's timing system.

Cam plate seals experience constant exposure to engine heat, oil, and rotational stress from the camshaft. Allstar's dual-material construction—combining a resilient rubber gasket with a steel backing plate—distributes clamping force evenly and resists thermal degradation over extended use. The compact dimensions (3.45 x 0.3 x 4.5 inches) ensure proper fit in standard small-block and mid-block engine configurations. This replacement seal is sold individually, so verify your engine's original seal specifications before ordering to confirm compatibility with your block and head assembly.

This cam plate seal is ideal for engine builders, restoration shops, and performance enthusiasts performing top-end overhauls, rebuilds, or maintenance on naturally aspirated and forced-induction engines. If your engine exhibits oil seepage around the front cam area or you're performing a complete gasket refresh during a head job, this OEM-style replacement restores proper sealing without modifications. Allstar Performance's reputation for precise engineering makes this seal a trusted choice for builders who demand reliable engine sealing.

Cam plate seals are often overlooked during maintenance, yet they account for a significant portion of front-end oil weeps in high-mileage and high-performance applications. Replacing a worn seal during a planned overhaul prevents costly oil loss and potential engine damage. The Allstar Performance ALL 90089 offers a straightforward, affordable solution that meets OEM specifications and delivers years of reliable service in demanding racing and street-engine environments.
