076103351E — Cylinder Head for Volkswagen BJJ, BJK, BJL, and BJM Engines

The BJJ 2.5D Cylinder Head Assembly (commonly used in VW 2.5 TDI 10V engines; Part Numbers: 076103351E / 908713) is a component designed for five-cylinder diesel engines. Its key technical specifications include: the use of a Multi-Layer Steel (MLS) cylinder head gasket (with a thickness of 1.53 mm – 1.57 mm); a maximum cylinder head distortion limit of 0.1 mm (0.004 inches); and the requirement that the cylinder head bolts must be replaced.

Description

Key Technical Specifications and Details
Engine Type: 2.5L Diesel Engine (TDI), 10-valve (2 valves per cylinder). Cylinder Head Gasket Thickness: 1.53 mm – 1.57 mm (varies by manufacturer; typically corresponds to a 1-hole or 2-hole gasket).
Gasket Design: Multi-Layer Steel (MLS) construction.
Piston Protrusion: Typically 0.81 mm – 0.96 mm; this measurement is used to determine the required cylinder head gasket thickness.
Cylinder Head Warpage Limit: Maximum 0.1 mm (0.004 in).
Required Components: New cylinder head bolts and a new cylinder head gasket must be used during assembly. Tightening Sequence: Bolts must be tightened using a “center-out” sequence to ensure uniform clamping pressure distribution.
