NISSAN PATROL III/2 Hardtop 1986.05-1990.06 2.8 TD (85KW,116PS) RD28-TI RD28TI RD28 Cylinder Head 1104020V02 11040G9825 2826cc SOHC 12v 908501 – OEM 908501

Product Overview: This complete cylinder head assembly is engineered for the Nissan RD28, RD28-TI and RD28TI 2.8-litre inline six-cylinder diesel engines, a proven powerplant used in the Patrol, Laurel, Cedric and Crew models. It is supplied fully assembled with valves, guides and seats installed and is machined to original equipment tolerances, providing a reliable replacement for a cracked, warped or valve-damaged original cylinder head.

Key Features: The head is cast from high-quality aluminium alloy with cast iron valve seats and CNC-machined for accurate deck flatness, correct valve seat concentricity and consistent combustion chamber volume across all six cylinders. The SOHC 12-valve valvetrain is supported by machined cam journals that maintain correct bearing clearance, and valve guides and seats are pre-installed and honed for even sealing and balanced compression. Injector seats are precisely cut for correct diesel combustion, and the intake and exhaust flanges are finished for reliable gasket sealing.

Vehicle Compatibility: This head fits Nissan Patrol III/2 Hardtop and Station Wagon 2.8 TD and 2.8 D models (1986-1996, 66-85 kW / 90-116 PS), Laurel 2.8 D (1985-1989), Cedric and Crew applications (1983-2010) and related Patrol GR models fitted with the RD28 engine. Confirm the engine code and OE reference before ordering.

Specifications: Engine code RD28; displacement 2.8 litres (2826 cc); inline six-cylinder diesel; SOHC 12-valve; material aluminium alloy casting with cast iron valve seats; standard size; new condition; complete assembly; 12-month warranty; purpose replacement and repair.

OEM / Reference Numbers: 908501, 1104020V02, 11040G9825, 1104120V01, 1104120V90 and 1104120V91. Match these references against the casting marks on the original head to confirm the correct variant.

Applications: Suitable for off-road SUVs, station wagons, pickups and passenger cars, covering everyday repairs, engine rebuilds, workshop overhauls and fleet maintenance where a durable factory-specification diesel head is required.

Benefits / Replacement Information: Fitting this assembly restores compression, corrects coolant and combustion leakage caused by cracking or distortion, and removes the cost and delay of re-machining the original casting. The complete assembly ensures matched valve and seat geometry for dependable long-term sealing.

Installation or Fitment Notes: Installation should be performed by a qualified technician. Verify block deck flatness, fit a new head gasket and new head bolts where specified, and torque in the correct sequence to the manufacturer's specification. Check valve clearances and injection timing after assembly, then pressure test and bleed the cooling system before road use.
