Reassembly
Reassembly
NOTE:
- Thoroughly clean all parts to be assembled.
- Before installing the parts, apply fresh engine oil to all sliding and rotating surfaces.

Incorrect installation of the seal could result in oil leakage past the valve guides.
- Reassemble the valve stem seals
(2) After applying engine oil on the outer surface of each valve stem, insert the valve in the valve guide.
Install the valve, valve spring and spring retainer.
NOTE:
When installing valve springs, the side coated with enamel should face toward the valve spring retainer
(3) Using the SST(09222 - 3K000, 09222-3C300), compress the springs and install the retainer locks. After installing the valves, ensure that the retainer locks are correctly in place before releasing the valve spring compressor.

Tightening torque
66.7 - 78.5Nm(6.8 - 8.0kgf.m, 49.2 - 57.9lb-ft)
NOTE:
After tightening the CVVT bolts, rotate the CVVT assembly housing counterclockwise by hand to seat the lock pin in the CVVT assembly in good position.
CAUTION:
Fix the hexagonal part of the camshaft in a vice when tightening the CVVT bolts. Do not fix the CVVT housing or sprocket in a vice.
4. Install the camshaft in the cylinder head assembly.
(1) Align the timing mark of the camshaft timing chain.
LH Camshaft Chain Timing Mark
RH Camshaft Chain Timing Mark
CAUTION:
Both timing marks should face upward in reassembly.
5. Install the timing chain tensioner.
(1) Insert the set pin by pressing the timing chain tensioner.
(2) Install the chain tensioner(A) in the cylinder head assembly.
6. Install the camshaft bearing caps.
Tightening torque
Bearing cap bolt(A: 6•38) :
10.8 - 12.7Nm(1.1 - 1.3kgf.m, 8.0 - 9.4lb-ft)
Bearing cap bolt(B: 8•38) :
20.6 - 22.5Nm(2.1 - 2.6kgf.m, 15.2 - 18.8lb-ft)
NOTE:
When installing the bearing caps, check the marks on them as shown below and install them in its proper position.
A(LH/RH HEAD): L(LH), R(RH)
B(Intake/Exhaust): I(Intake), E(Exhaust)
C(Cap no.): 1,2,3
CAUTION:
When installing the bearing caps, turn the crankshaft to place a piston in the middle of the block because interference between valves and pistons can occur.
7. Using the SST(09214-21000), install the camshaft oil seal.
NOTE:
- Before installing, apply engine oil.
