Remove the left cylinder head gasket.

Refitting ( Removing

) Fit a new left cylinder head gasket.

ASTADUR type cylinder head gaskets are fitted. The material from which these gaskets are made undergoes a polymerization process during the operation of the engine so that they become considerably harder during usage.

In order for the polymerization of the gasket to take place it is necessary to:

keep the gasket in its sealed container until fitting
not lubricate or get oil on the gasket and the contact surfaces.

Place the left cylinder head back in its housing.

Two operators are needed for this operation.

1. Tighten the nuts for the left cylinder head (1a) to the recommended torque using the angular tightening tool (1b).
