REMOVAL
1. Remove engine assembly from vehicle. Refer to EM-237, "Component".
2. Remove camshaft relating to valve oil seal to be removed. Refer to EM-211, "
Component".
3. Remove valve lifters. Refer to EM-211, "

ment and adapter (SST). Remove valve collet with magnetic
hand.
CAUTION:
When working, take care not to damage valve lifter holes.
6. Remove valve spring retainer and valve spring (with valve spring seat). CAUTION:
Do not remove valve spring seat from valve spring.
7. Remove valve oil seal using valve oil seal puller (SST).
INSTALLATION
1. Apply new engine oil on new valve oil seal joint and seal lip.
2. Install valve oil seal.  Install with valve oil seal drift (SST) to match dimension in the
figure.
3. Install in the reverse order of removal.

DISASSEMBLY
NOTE:
Explained here is how to disassemble with engine stand supporting transmission surface. When using differ-
ent type of engine stand, note with difference in steps and etc.
1. Remove engine assembly from vehicle, and separa te front suspension member, transmission and front
final drive from engine. Refer to EM-237, "
Component".
2. Remove the parts that may restrict installation of engine to widely use engine stand. NOTE:
The procedure is described assuming that you use wi dely use engine holding the surface, to which trans-
mission is installed.
a. Remove drive plate.  Holding ring gear with ring gear stopper (SST).
 Loosen mounting bolts diagonally order.
CAUTION:
 Do not disassemble drive plate.
 Do not place drive plate with signal plate facing down.
 When handling signal plate, take care not to damage or scratch it.
 Handle signal plate in a manner that prevents it from becoming magnetized.
b. Remove engine rear plate.
3. Lift engine with hoist to install it onto widely use engine stand. CAUTION:
Use engine stand that has a load capacity [approximately 240 kg ( 529 lb) or more] large enough for
supporting the engine weight.
 If the load capacity of stand is not adequate, remo ve the following parts beforehand to reduce the poten-
tial risk of overturning stand.
- Intake manifolds (upper and lower): Refer to EM-175, "
Component".
- Exhaust manifold: Refer to EM-179, "
Component".
- Fuel tube and fuel injector assembly: Refer to EM-190, "
Component".
