Sealing joints
The engine has wet cylinder liners for effective heat
removal. They are sealed against the cylinder block
by rubber rings. The uppermost ring is located imme-
diately below the liner collar (
A
). The liner sealing sur-
face against the cylinder head gasket is convex.
The lower seal comprises three O-rings located in
grooves in the cylinder block (
B
). These rings are
made from different rubber materials and have differ-
ent colors to prevent confusion. The two upper (black)
rings are made from EPDM rubber and are therefore
resistant to coolant, while the lower (purple) is fluoro-
rubber and resistant to oil.
The gasket (
C
) between the cylinder head, block and
liner is made from steel and has integral vulcanized
rubber seals for the coolant and oil channels. In order
to protect the rubber seals during cylinder head instal-
lation, the gasket has a number of convex indenta-
tions for the cylinder head to glide on. These inden-
tations are flattened when the cylinder head is bolted
in place.
