1.
Install the CVVT assembly (A) to the camshaft.
Tightening torque :
64.7 ~ 76.5 N.m (6.6 ~ 7.8 kgf.m, 47.7 ~ 56.4 lb-ft)

  
When installing the CVVT assembly bolt, hold the camshaft with a wrench to prevent the camshaft from rotating.
2.
Compress the tensioner plunger using a pry bar (A) and then insert the stopper pin (B) into the hole in the tensioner to hold the compressed plunger.
3.
Place the intake camshaft (A) and then insert the tensioner arm (B) along the timing chain.

4.
Place the exhaust camshaft (A).

  
The timing marks of each CVVT sprocket should be matched with timing marks (painted link) of timing chain when installing the timing chain.

5.
Install the camshaft bearing caps.

Tighten the bolts, in several passes, in the sequence as shown.
Tightening torque
M6 bolts:
11.8 ~ 13.7 N.m (1.2 ~ 1.4 kgf.m, 8.7 ~ 10.1 lb-ft)
M8 bolts:
18.6 ~ 22.6 N.m (1.9 ~ 2.3 kgf.m, 13.7 ~ 16.6 lb-ft)

  
Be careful not to change the position and direction of bearing caps.
6.
Using a suitable tool, move the tensioner arm to align the tensioner bolt hole with the service hole.

7.
Install the tensioner arm bolt (A).
Tightening torque:
18.6 ~ 22.6 N.m (1.9 ~ 2.3 kgf.m, 13.7 ~ 16.6 lb-ft)

8.
Remove the stopper pin from the tensioner.
9.
Turn the crankshaft two turns in the operating direction (clockwise), and then check that the TDC marks of the CVVT sprockets are in straight line on the cylinder head surface.

10.
Install a service plug bolt (A) with a gasket.
Tightening torque:
29.4 ~ 39.2 N.m (3.0 ~ 4.0 kgf.m, 21.7 ~ 28.9 lb-ft)

  
Do not reuse the service plug bolt and gasket.
11.
Install the crankshaft damper pulley.
(Refer to Timing System - “Crankshaft Damper Pulley”)
