Passat 1991-1993 1.8 GL CEAA CGMA CGM BYJCCUA CRHA Cylinder Head 06J103063B for VW EA888 Engine – OEM 06J103063B

Product Overview: This complete cylinder head assembly is manufactured for the Volkswagen and Audi 1.8 and 2.0-litre petrol engines in the EA888 family, including CEA, CGMA, BYJ, CUA and CRHA engine codes. It is supplied fully assembled with valves, guides and seats installed and is machined to original equipment tolerances, providing a reliable 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 for even sealing and balanced compression across all four cylinders, and the cam carrier surfaces are finished to maintain correct bearing clearance in the DOHC valvetrain. Intake and exhaust flanges are machined to original profiles for reliable gasket sealing, while cooling passages follow the factory layout for uniform heat distribution.

Vehicle Compatibility: This head fits Volkswagen Passat 1.8 GL and 1.8-litre models (1991-1993) and related Volkswagen and Audi applications that use the EA888 engine with the listed engine codes. Because these engines were produced in many variants, always confirm the engine code, casting number and OE reference against the original component before ordering.

Specifications: Engine code CEAA / CGMA / CGM / BYJ / CUA / CRHA; displacement 1.8 L and 2.0 L; inline four-cylinder petrol; DOHC; material cast iron or aluminium; standard size; new condition; complete assembly; 12-month warranty; intended for replacement and repair.

OEM / Reference Numbers: 06J103063B and 06J103063A. Cross-reference these numbers with the casting marks and part label on the original cylinder head to confirm the correct variant.

Applications: Suitable for passenger cars, sedans, hatchbacks and small SUVs, covering everyday repairs, engine rebuilds, workshop overhauls and fleet maintenance where a factory-specification petrol head is required.

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

Installation or Fitment Notes: Installation should be carried out by a qualified technician. Clean and check the block deck for flatness, use new head bolts where specified, and torque in the correct sequence to the manufacturer's specification. Replace the head gasket, timing components and coolant, verify cam timing and valve clearances, then pressure test and bleed the cooling system before road use.
