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.
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 timinig chain.
LH camshaft chain timing mark
RH camshaft chain timing mark
Both timing marks should face upward in reassemby.
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)
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
When installing the bearing caps, turn the crankshaft to place a piston in the middle of the block because
linterference between valves and pistons can occur.

The length of the bolt(B) is longer than that of the bolt(C).
11. Install the timing belt.(Refer to 'Timing system').
12. Check and adjust the valve clearance.
13. Install the cylinder head cover.
(1) Remove oil, dust or sealant on the upper surface of the cylinder before assembling cylinder head cover.
(2) Assemble the cylinder head cover in five minites after applying liquid gasket(LOCTITE 5900) on the camshaft
cap and packing part.
(3)Tighten the cylinder head cover bolts as following order(A).
Tightening torque
7.8~9.8Nm(0.8~1.0kgf.m, 5.8~7.2lb- ft)
Page 57 of 1575
(4)Install the bearing caps with the tightening torque.
Do not turn the camshaft.
(5) Remove the bearing caps.
(6) Measure the plastigage at its widest point.
Bearing oil clearance
[Standard value]
Intake : 0.020 ~ 0.057mm (0.0008 ~ 0.0022in.)
Exhaust : 0.020 ~ 0.057mm (0.0008 ~ 0.0022in.)
If the oil clearance is greater than the maximum, replace the camshaft. If necessary, replace the cylinder head.
(7) Completely remove the plastigage.
(8) Remove the camshafts.
4. Inspect camshaft end play.
(1) Install the camshafts.
(2) Using a dial indicator, measure the end play while moving the camshaft back and forth.
Camshaft end play
[Standard value] : 0.05 ~ 0.15mm(0.0020 ~ 0.0059in.)

(4)Lightly tap the end of each valve stem two or three times with the wooden handle of a hammer to ensure
proper seating of the valve and retainer lock.
2. Install MLAs with engine oil applied on its surface.
Check that the MLA rotates smoothly by hand.
MLA should be reinstalled in its original position.
3. Install OCV(Oil Control Valve)(A).
Tightening torque
7.8 ~ 9.8Nm(0.8 ~ 1.0kgf.m, 5.8 ~ 7.2lb - ft)
a.To install OCV with gray colored connector into RH bank.
b. To install OCV with black colored connector into LH bank.
