REMOVAL
1. Remove camshafts. Refer to EM-170, "Component".
2. Remove valve lifters. Refer to EM-170
.
3. Rotate crankshaft, and set piston whose valve oil seal is to be removed to TDC. This will prevent valve from dropping into cylinder.

4. Remove valve collet. • Compress valve spring using Tool, the attachment and the
adapter (A). Remove valve collet with a suitable magnet hand
(B).
CAUTION:
When working, be careful not to damage valve lifter holes.
5. Remove valve spring retainer, valve spring and valve spring seat.
6. Remove valve oil seal using Tool (A).
INSTALLATION
1. Apply new engine oil to valve oil seal joint surface and seal lip.
2. Press in valve oil seal to the height (H) shown using Tool (A).
3. Installation of the remaining components is in the reverse order of removal.

• If clearance exceeds the limit, select proper main bearing according to main bearing inner diameter and
crankshaft main journal diameter to obtain specified bearing oil clearance. Refer to EM-212, "
How to Select
Piston and Bearing".
Method of Using Plastigage
• Remove engine oil and dust on crankshaft main journal and the surfaces of each bearing completely.
• Cut a plastigage slightly shorter than the bearing width, and place it in crankshaft axial direction, avoiding oil
holes.
• Install main bearings to cylinder block and main bearing cap, and tighten main bearing cap bolts to the spec- ified torque. Refer to EM-203, "
Disassembly and Assembly" for the tightening procedure.
CAUTION:
Never rotate crankshaft.
• Remove main bearing cap and bearings, and using the scale (A) on the plastigage bag, measure the plastigage width.
NOTE:
The procedure when the measured value exceeds the limit is
same as that described in the “Method by Calculation”.
MAIN BEARING CRUSH HEIGHT
• When main bearing cap is removed after being tightened to thespecified torque with main bearings (1) installed, the tip end of
bearing must protrude (B). Refer to EM-203, "
Disassembly and
Assembly" for the tightening procedure.
• If the standard is not met, replace main bearings.
CONNECTING ROD BEARING CRUSH HEIGHT
• When connecting rod bearing cap is removed after being tightened to the specified torque with connecting rod bearings (1) installed,
the tip end of bearing must protrude. Refer to EM-203, "
Disassem-
bly and Assembly" for the tightening procedure (B).
• If the standard is not met, replace connecting rod bearings.
