200 TROUBLESHOOTING
If replacing less than a full set of six sleeves, use
the same original production sleeve. For each
sleeve replaced, use a new crevice seal and
apply Silastic at the cylinder block sleeve seat.
Depending on their condition, new piston ring
sets may also be needed. O-rings are no longer
used in the cylinder block groove below the
sleeve seats.
When it is necessary to replace all the sleeves,
use the new full-contact type sleeves with flat fire
rings. Also use new crevice seals, Silastic and
new piston ring sets. O-rings are no longer used
in a groove in the cylinder block below the sleeve
seats.
Some engines built before June 1993 may be
fitted with sleeves which use flat fire rings. Always
visually examine all six sleeves to determine
which sleeve-top configuration applies.
If replacing head gaskets with original parts, use
the sleeve-top configuration shown in Figure 9-1
and the cylinder gasket kit with the stepped fire
ring.
Engines Built from June 1993 to
Present (3L Serial Number and Later)
Refer to Figure 9-2.
E7 engines built since June 1993 use the full-
contact type of cylinder sleeve. This sleeve
provides full-contact support for the flat fire ring.
If replacing sleeves, either a full or partial set, use
the same type sleeve. For each sleeve replaced,
use a new crevice seal and apply Silastic to each
cylinder block sleeve seat. Depending on their
condition, new piston ring sets may also be
needed for each sleeve replaced. O-rings are no
longer used in the cylinder block groove below
the sleeve seats.
