Fit a new right cylinder head gasket.
The cylinder head gasket is of the Astadur type.
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.
Fit the right cylinder head on the cylinder block.1. Tighten the nuts for the left cylinder head (1a) to the recommended torque using the angular tightening tool (1b).
Follow the order shown in the diagram for each tightening sequence.
