This rubber seal is a washer-type gasket used on the rocker cover of Land Rover's 2.25 Petrol engine, providing a compression seal around the rocker cover fixing bolts or studs to prevent oil leakage at that joint. On the 2.25 Petrol, deteriorated or hardened washer seals are a common cause of minor oil weeps from the rocker cover area, which can result in oil contaminating the engine bay or dripping onto exhaust components. Correct replacement with a properly dimensioned rubber seal restores the required compression and prevents recurrence.
