01400 Repair notes for cylinder and cylinder head gaskets
602, 603
Differentiation of cylinder heads for naturally
aspirated and turbo-engines
The cylinder heads for turbo-engines 602.96,
603.96 and 603.97 are reinforced at the water
jacket due to the higher combustion pressures.
On turbo-engines the diameter (d) of the
combustion chamber bore is 15 mm, on naturally
aspirated engines 14 mm.
The cylinder heads on turbo-engines are pro-
vided with an identification strip. This identi-
fication strip (arrow) is located on the parting
surface for the cylinder head cover at the front
right.
Caution!
Do not mix up cylinder heads for turbo-engines
and naturally aspirated engines.
