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.

NOTE: TECHNICAL INFORMATION
Cylinder head gasket interchange leads to engine damage. Check identification on cylinder head gasket.
Check number of holes of the old cylinder head gasket:
Check all fitting sleeves for tightness and for damage (1) , replace if necessary.
Replace cylinder head gasket (2) .
Parts: Cylinder head gasket
