Maintain a secure and leak-free rocker cover seal with this Genuine Nissan Rocker Cover Rubber Washer, designed specifically for Nissan Patrol GQ Y60 and GU Y61 models fitted with TB42, TD42, and TB45 engines. This OEM rubber washer is fitted beneath the rocker cover retaining hardware and helps distribute clamping force while creating a reliable seal around the mounting points.

Over time, rocker cover rubber washers are exposed to constant engine heat, oil exposure, and compression cycles. As the rubber ages, it can harden, flatten, crack, or lose its sealing ability, allowing oil to seep past the rocker cover mounting points and contribute to engine oil leaks.

Manufactured to genuine Nissan specifications, this direct-fit replacement restores correct sealing pressure and helps maintain the integrity of the rocker cover gasket and valve cover assembly.
