Installation

• Fit a new cylinder head gasket on the cylinder block.

Note: The new gasket must be of the same thickness as the old one.

Note: The cylinder head gasket is of the Astadur type. On account of the special material from which these gaskets are made they undergo a polymerization process during the operation of the engine so that they become considerably harder during usage.

Note: In order for the polymerization process to take place it is necessary to:

• keep the gasket in its sealed nylon container until fitting
• not to take out of its container until ready to fit
• not lubricate or get oil on the gasket
• Position the cylinder head on the crankcase.
• Lubricate the bolts and washers and leave them to drain for at least 30 minutes.
• Insert the bolts and finger tighten them.
• See Op. 1072C16 Exhaust manifold with catalytic converter - r r

1. Tighten the cylinder head bolts to torque in accordance with the sequence shown in the figure.

• Further tighten the cylinder head bolts to torque in accordance with the sequence shown in the figure.

2. Further tighten the cylinder head bolts in two stages to a total angular rotation of 180 (90 + 90) using the tool.
