Keep your Nissan Patrol’s ZD30 engine properly sealed with this Genuine Nissan Timing Cover O-Ring, designed specifically for GU Y61 models fitted with the ZD30 diesel engine. This OEM seal sits between the timing cover and engine block, forming part of the critical sealing system that prevents engine oil leaks from the front of the motor.

Over time, this O-ring can harden, flatten, or crack due to heat cycles, oil exposure, and engine age. When it begins to fail, it commonly causes oil leaks from the timing cover area, which can lead to a messy engine bay, reduced oil levels, and potential long-term engine wear if not addressed.

Manufactured to Nissan’s original specifications, this direct-fit replacement ensures accurate sealing, correct fitment, and long-lasting durability in both on-road and off-road conditions.
