Base gasket thickness
This engine is manufactured with two different head gasket solutions:
- Fibre gasket drw. 969244 0.95 mm thick.
- Steel gasket drw. 969393 0.3 mm thick.
In order to guarantee an adequate compression ratio, the gaskets match cylinders with different heights:
- Fibre gaskets with cylinder 56.45 mm high
- Fibre gaskets with cylinder 57.15 mm high
In order to carry out the revision both gaskets should be present on the spare parts.
All pin-piston-cylinder units supplied with the spare parts present cylinders 57.15 mm high
