Set No.1 cylinder to TDC (Top dead center) on compression stroke.
Turn the crankshaft pulley and align its groove with the timing mark of the timing chain cover.
Check that the TDC marks of the intake and exhaust CVVT sprockets are in straight line on the cylinder head surface as shown in the illustration. If not, turn the crankshaft by one revolution (360°) more.
Mark the timing chains corresponding to the timing marks of the CVVT sprockets.

To make the piston of the tensioner compressed, loose the chain, pushing the tensioner arm by a handy bar (A).
Disconnect the chain, slightly lifting the exhaust camshaft.
Remove the exhaust camshaft assembly (B).
To hold the timing chain, tie it with strap.
Remove the CVVL position sensor (A). (Refer to FL group)
Remove the CVVL position sensor magnet wheel (A). (Refer to FL group)
Remove the CVVL shaft bearing cap (A).
Remove the CVVL assembly (A).
Remove the intake camshaft assembly (A).

Install the intake camshaft assembly (A).
Install the CVVL assembly (A).
Install the CVVL assembly with the CVVL motor removed.
It may cause damage to the warm gear of CVVL motor that CVVL shaft bearing cap is reinstalled after installing the CVVL motor.
Install the CVVL shaft bearing cap (A).

Tightening torque :
9.8 ~ 11.8N.m (1.0 ~ 1.2kgf.m, 7.2 ~ 8.7lb-ft)
Install the exhaust camshaft assembly.
Install the timing chain to intake CVVT sprocket, align the timing mark.
To make the piston of the tensioner compressed, loose the chain, pushing the tensioner arm by a handy bar (A).
Install the timing chain to exhaust CVVT sprocket, align the timing mark.
Install the exhaust camshaft assembly (B).
The timing marks of each CVVT sprocket should be matched with timing marks (painted link) of timing chain when installing the timing chain.
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.
Disconnect the long nose pliers form the chain tensioner.
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.
If TDC mark of CVVT sprocket is not align, reinstall the timing chain.
Install the cam to cam guide (A).
Tightening torque :
9.8 ~ 11.8N.m (1.0 ~ 1.2kgf.m, 7.2 ~ 8.7lb-ft)
