Prevent costly engine oil leaks with this Genuine Nissan Rear Main Seal, designed for Nissan Patrol GQ Y60 RB30 petrol and GQ/GU RD28 diesel engines. This OEM crankshaft oil seal is fitted at the rear of the engine where the crankshaft exits the engine block and connects to the flywheel or flexplate, providing a critical seal that prevents engine oil from escaping into the bellhousing.

Over time, rear main seals naturally harden, shrink, and wear due to constant heat cycles, crankshaft rotation, and engine oil exposure. When the seal begins to fail, oil can leak into the clutch housing or transmission bellhousing area, resulting in oil contamination, clutch slippage, unpleasant oil smells, and progressive oil loss. Because replacement requires removal of the gearbox, it is highly recommended to replace the rear main seal whenever performing clutch or major engine work.

Manufactured to genuine Nissan specifications, this direct-fit replacement seal restores factory oil sealing performance and helps protect your engine and drivetrain from oil contamination.
