Maintain proper engine oil sealing and prevent unwanted oil leaks with this Genuine Nissan Dipstick Tube O-Ring, designed for Nissan Patrol GU Y61 models fitted with the ZD30 diesel engine. This OEM rubber seal is fitted at the base of the dipstick tube where it enters the engine block, ensuring a tight and reliable seal under all operating conditions.

Over time, the original dipstick tube O-ring can harden, shrink, or crack due to heat cycles and engine oil exposure. When this occurs, it may result in engine oil leaks around the dipstick tube, oil loss, or in some cases the dipstick tube becoming loose in the engine block. Ignoring a failed O-ring can lead to reduced oil levels and potential engine damage if not addressed promptly.

Manufactured to Nissan factory specifications, this genuine replacement O-ring ensures correct fitment, long-lasting durability, and reliable sealing performance. It is an essential and low-cost maintenance item when servicing or repairing the dipstick tube on your ZD30-powered Patrol.
