The cylinder head is made of cast iron, and each cylinder has
its own inlet port and common exhaust port. The stiffness and
even spread of attaching bolts give a good seal for the cylin-
der head gasket. The directed flow of the coolant ensures that
the valve seats are effectively.

3. O---ring seals
The inlet and exhaust valve guides (1) are identical and can
be interchanged. The injectors are surrounded by replace-
able copper sleeves (2) which are in contact with the coolant,
thus the injectors are effectively cooled.
