NOTE: Schematic diagram is for example purposes. Some parts may differ in certain details.

NOTE: TECHNICAL INFORMATION
If no work has been done on the engine block that changes the piston protrusion, use a new cylinder head gasket with the same gasket thickness.
If work has been done on the crankshaft drive or piston, the gasket thickness must be determined again.
