d. Tighten front cover bolts in the numerical order shown.
e. After all bolts are tightened, retighten them to the specified torque.
CAUTION:
Wipe off excess sealant leaking at the surface for installing
the oil pan.
10. Install the chain guide between the camshaft sprockets.
11. Install valve timing control cover. Refer to EM-59, "Valve Timing Control Cover"
.
12. Insert crankshaft pulley by aligning with crankshaft key. • Tap its center with a plastic hammer to insert.
• Do not tap the crankshaft pulley outer diameter.
13. Tighten crankshaft pulley bolt. • Secure crankshaft pulley with tool to tighten the bolt.
• Perform angle tightening with the following procedure:
a. Apply new engine oil to threads and seat surfaces of bolts.
b. Tighten to initial specifications:
c. Apply a paint mark (A) on the front cover, mating with any one of six easy to recognize stamp marks on bolt flange (B).
d. Turn crankshaft pulley bolt an additional 60 degrees +6/-0 degrees.
NOTE:
Check that the assembled unit does not interfere with adjacent
components by turning the crankshaft in the tightening direction.
14. Installation of the remaining components is in the reverse order of removal.Front cover bolts

REMOVAL
1. Remove camshaft. Refer to EM-47, "Removal and Installation".
2. Remove valve lifter. Refer to EM-47, "Removal and Installation"
.
3. Rotate crankshaft, and set piston whose oil seal is to removed to top dead center. This prevents valve from dropping inside cylinder.
CAUTION:
When rotating crankshaft, be careful to avoid scarring the front cover with the timing chain.
4. Remove valve collet. • Compress valve spring using Tools. Remove valve collet with
magnet hand.
CAUTION:
• Be careful not to damage valve lifter holes.
• Install Tool (A) in the center of valve spring retainer to
press it.
5. Remove valve spring retainer and valve spring (with valve spring seat). CAUTION:
Do not remove valve spring seat from valve spring.
6. Remove valve oil seal using Tool (A).
INSTALLATION
1. Apply new engine oil to new valve oil seal joint surface and seal lip. Tool number (A) : KV10116200 (J-26336-A)

ENGINE ASSEMBLY
NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal and installation, slack in the guide
may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop
after hydraulic pressure rises.
• Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gas, or any oils/fluids including engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec- ified level, if necessary.

.
14. Remove the knock sensor. CAUTION:
Carefully handle the sensor and do not drop the sensor.
15. Remove crankshaft position sensor (POS) (2) and O-ring (1).
CAUTION:
• Avoid impacts such as a dropping.
• Do not disassemble.
• Keep it away from metal particles.
• Do not place sensor close to magnetic materials.
• Do not reuse O-ring.
16. Remove the piston and connecting rod assemblies.
a. Position the crankshaft and corresponding connecting rod, to be removed, to the bottom dead center stroke.
b. Remove the connecting rod cap. Number the cap so it can be assembled in the same position.
c. Using a hammer handle or similar tool, push the piston and con- necting rod assembly out of the top of the cylinder block. Num-
ber the piston and rod so it can be assembled in the same
position.
• Before removing the piston and connecting rod assembly,
check the connecting rod side clearance. Refer to EM-96,
"Inspection After Disassembly".
17. Remove the connecting rod bearings. If reusing, num ber them so they can be assembled in the same
position and direction.
CAUTION:
• When removing them, note the installation position. Keep them in the correct order.
18. Remove the piston rings from the piston. • Use a piston ring expander.
• Before removing the piston rings, check the piston ring side
clearance. Refer to EM-96, "Inspection After Disassembly"
.
CAUTION:
• When removing the piston rings, be careful not to damage
the piston.
• Be careful not to damage piston rings by expanding them excessively, if reusing them.
