Maintain proper engine sealing and oil pressure with this Genuine Nissan TB48 Timing Cover to Engine Block Large O-Ring, designed specifically for Nissan Patrol GU Y61 models fitted with the TB48 engine. This OEM sealing ring sits between the engine block and timing cover, ensuring a secure seal that prevents oil leaks from the front of the engine.

Over time, this O-ring can harden, flatten, or crack due to heat cycles, engine vibration, and age. A worn or damaged seal can result in oil leaks from the timing cover area, low oil levels, and potential engine damage if not addressed promptly.

Manufactured to genuine Nissan specifications, this direct-fit replacement ensures accurate sealing performance, correct fitment, and long-lasting durability in demanding Australian on-road and off-road conditions.
