NOTE:
Refer to the "Lubrication System" section
for installation torques of remote oil filter
and oil filter bypass components.
INSTALL OIL PRESSURE RELIEF VALVE,
CLOSURE PLATE, AND REAR OIL SEAL
NOTE:
Later production models use silicone sealant
as a gasket between the closure plate and
crankcase. In order to eliminate the fiber gas-
ket and use sealant, an additional .020" of
material was added to the closure plate.
Therefore, closure plates designed for use
with gaskets cannot be installed using sea-
lant; closure plates designed for use with sea-
lant cannot be installed using a gasket.
Follow these general guidelines when reinstalling or
replacing closure plates:
* When reinstalling a closure plate originally in-
stalled using a gasket, use a new gasket.
* When reinstalling a closure plate originally in-
stalled using sealant or installing a service re-
placement closure plate kit, apply a new bead of
sealant to the closure plate as shown in
Figure 11-27.
1. Instali the oil pressure relief valve sleeve, steel
ball, and spring. Refer to Figure 11-26.
2. Make sure the mating surfaces of the crankcase
and closure plate are cleaned and prepared as
directed by the sealant manufacturer.
Refer to
"INSTALL CAMSHAFT BORE PLUG AND SEAL
SECTION 11

mation on sealants.
