Maintain a proper oil-tight seal on your rocker cover with this Genuine Nissan Rocker Cover Metal Washer, designed specifically for Nissan Patrol GQ and GU models fitted with TB42, TB45, and TD42 engines. This OEM sealing washer sits under the rocker cover bolts and works together with the rubber washer to ensure even clamping force and a reliable seal across the valve cover.

Over time, metal washers can become flattened, distorted, or corroded due to repeated heat cycles, engine vibration, and previous servicing. A worn washer may prevent proper sealing pressure, leading to rocker cover oil leaks, oil seepage around bolt heads, and a generally messy engine bay.

Manufactured to genuine Nissan specifications, this direct-fit replacement restores correct sealing pressure, helping maintain a clean, leak-free rocker cover and long-term engine reliability.
