Campo 1986-1990 2.2 D Good Quality 4JB1 Cylinder Head 8-94327-269-0 8-94455-240-1 for Isuzu Pickup 2800/Trooper 2.8 – OEM 8972043765

Product Overview: This complete cylinder head assembly is manufactured for the Isuzu 4JB1 2.2-litre four-cylinder diesel engine, a robust and long-serving powerplant fitted to the Campo and related Isuzu pickup and utility models. It is supplied fully assembled with valves, guides and seats installed and is machined to original equipment dimensions, offering a practical replacement for a warped, cracked or valve-damaged original cylinder head.

Key Features: The casting is produced from high-grade material and CNC-machined for accurate deck flatness, correct valve seat concentricity and consistent combustion chamber volume. Valve guides and seats are pre-installed and honed to deliver even sealing and balanced compression across all cylinders, while the injector and pre-chamber seats are precisely machined to maintain correct fuel atomisation. Machined intake and exhaust flanges ensure reliable gasket sealing, and reinforced casting around the valve bridge improves durability under sustained diesel load.

Vehicle Compatibility: This head fits Isuzu Campo 2.2 D models (1986-1990) and related Isuzu Pickup 2800 and Trooper 2.8 applications that use the 4JB1 engine. Because the 4JB1 was used in a number of markets and configurations, always confirm the engine code, casting number and OE reference against the original component before ordering.

Specifications: Engine code 4JB1; displacement 2.2 litres; inline four-cylinder diesel; material cast iron or aluminium; standard size; new condition; complete assembly; 12-month warranty; designed for replacement and repair.

OEM / Reference Numbers: 8972043765, 8-94327-269-0, 8-94431-520-0, 8-94431-520-4, 8-94431-523-0, 8-94455-240-1, 8-97109-642-0 and 8-97109-643-1. These references cover several production revisions of the same basic casting, so cross-check them with the original head.

Applications: Suitable for light pickups, utility vehicles, small trucks and industrial equipment powered by the 4JB1, as well as general workshop repairs, engine rebuilds and fleet maintenance programmes where a durable factory-specification diesel head is required.

Benefits / Replacement Information: Installing this assembly restores compression, corrects coolant loss and combustion leakage caused by cracks or distortion, and avoids the expense of separately re-machining the original casting. A complete unit shortens repair time and delivers consistent, factory-matched sealing.

Installation or Fitment Notes: Fitment should be carried out by a qualified technician. Clean and check the block deck for flatness, fit a new head gasket and new head bolts where specified, and torque in the correct sequence to the manufacturer's figures. Verify valve clearances and injection timing after assembly, then pressure test and bleed the cooling system before returning the vehicle to service.
