Technical Specification Preview

Accurate internal reference values are essential for engine diagnostics and reassembly. The guide documents cylinder head bolt torque values in a multi-stage sequence to guarantee clamping uniformity. For the intake, valve clearance is listed at 0.30 mm within the assembly data. Maintaining ignition efficiency relies on a precise spark plug gap, specified here at 1.1 mm. The publication also reviews testing procedures for cylinder head gasket integrity and combustion chamber pressure, helping you identify performance deviations quickly.
