VW TRANSPORTER T4 Van 1992.10-1998.09 2.4 D Syncro (57KW,78PS) Aluminum AAB AJA AJB Cylinder Head 074103351A 074103265X for VW Volkswagen 2.4D 10V – OEM 908157

Product Overview: This aluminium cylinder head assembly is engineered for the Volkswagen 2.4-litre diesel engines in the AAB, AJA and AJB family, the proven powerplants used in the Transporter T4 and California T4 models. It is supplied fully assembled with valves, guides and seats installed and is machined to original equipment tolerances, offering a durable replacement for a cracked, warped or valve-damaged original cylinder head.

Key Features: The casting is produced from high-grade aluminium alloy 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 for even sealing and balanced compression across all cylinders, and the cam carrier surfaces are finished for correct bearing clearance. Injector seats and pre-chamber bores are precisely machined to maintain correct diesel combustion, while the intake and exhaust flanges are finished for reliable gasket sealing.

Vehicle Compatibility: This head fits Volkswagen Transporter T4 Van 2.4 D and 2.4 D Syncro (1992.10-1998.09), Transporter T4 Bus 2.4 D (1990-2003), Transporter T4 Platform/Chassis and California T4 Camper 2.4 D (1998-2002) models equipped with the AAB, AJA or AJB engine. Confirm the engine code and OE reference before ordering.

Specifications: Engine code AAB / AJA / AJB; displacement 2.4 litres; inline diesel; material aluminium alloy; standard size; new condition; complete assembly; 12-month warranty; purpose replacement and repair.

OEM / Reference Numbers: 908157, 908057, 074103351A, 074103265X and 074103351D. Cross-reference these numbers with the casting identification on the original cylinder head to confirm the correct variant is supplied.

Applications: Suitable for vans, buses, campers and light commercial vehicles, covering everyday repairs, engine rebuilds, workshop overhauls and fleet maintenance where a durable factory-specification diesel head is required.

Benefits / Replacement Information: Installing this assembly restores compression, corrects coolant and combustion leakage caused by cracking or distortion, and avoids the expense of re-machining the original casting. A complete unit keeps commercial vehicles in service with minimal downtime.

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 returning the vehicle to service.
