Position the cylinder head gasket.
Refit the cylinder head, lubricate the threads and
the bearing faces under the heads of the bolts
with engine oil.
Note : check the length of the bolts for the
cylinder head, the shorter ones are used on the
inlet side.

The central floor of the E64 vehicle is identical to
that of the B64 and about the same length. The
E64 part can be obtained from the B64 part by
cutting the rear section by 112 mm as shown on
the diagram below.
The complete changing of this part is a basic ope-
ration to be carried out in the event of an impact
underneath the vehicle when coming off the
road.
In this case, these additional parts must be orde-
red:
- the tunnel strengthener assembly,
- the instrument panel console bracket and
sheath end.
This part can be partially changed by cutting as
described in the following pages in the event of a
side impact in addition to a sill panel or an "A"
post.
