Isuzu Campo 1986-1990 4JB1 4JB1 4JB1-T Engine Parts Cylinder Head OEM 8972043765 8944315230 for Isuzu – OEM 8972043765

Product Overview: This complete cylinder head assembly is manufactured to original equipment standards for the 4JB1 petrol engine used across Isuzu Campo and related applications. It is supplied fully assembled with finish-machined camshaft journals, valve seats, valve guides and combustion chambers, so a cracked, warped or valve-damaged original head can be replaced without additional machining work.

Key Features: The casting is CNC-machined to original equipment tolerances for accurate deck flatness, correct valve seat concentricity and consistent combustion chamber volume across every cylinder. Valve guides and seats are pre-installed and honed for even sealing and balanced compression, and the high-grade aluminium alloy construction with reinforced walls around the valve bridge and fire deck improves durability under sustained thermal and mechanical load. Spark plug threads, cam carrier surfaces and port geometry are finished precisely to preserve correct bearing clearance and efficient gas flow in the petrol combustion cycle.

Vehicle Compatibility: This assembly is compatible with Isuzu Campo (1986-1990). Typical production coverage spans 1986-1990, although availability varies by market and model year.

Specifications: Engine code 4JB1; four-cylinder petrol configuration; material high-grade aluminium alloy; Standard Size; new condition; supplied as a complete assembly; 12 Months warranty; place of origin Chongqing, China; intended for replacement and repair use.

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-reference them with the casting marks and part label on the original component to confirm the correct variant.

Applications: Suitable for Isuzu Campo, covering everyday repairs, engine rebuilds, workshop overhauls and fleet maintenance where a factory-specification component is required. It is well suited to family cars, hatchbacks, sedans and small SUVs used in daily driving, as well as workshop overhauls and preventive maintenance programmes.

Benefits / Replacement Information: Installing this assembly restores lost compression, corrects coolant loss and combustion leakage caused by cracking or distortion, and removes the expense of machining and rebuilding the original head. A correctly specified replacement reduces the risk of repeat failure, helps restore original fuel economy and emissions performance, and returns the engine to reliable service with a predictable service life.

Installation or Fitment Notes: Confirm the engine code 4JB1 and OE number before ordering, and inspect the block deck and piston protrusion for flatness and correct height before fitting. Use new gaskets, head bolts and seals during installation, follow the manufacturer's torque sequence and tightening values, and refill with the correct grade of oil and coolant.
