Install the valve lifter.
- Install them in the same position from which they were removed.
Install the camshafts.
- The distinction between the intake and exhaust camshafts is in a difference of shapes of the back end:
  Intake: Signal plate for the camshaft position sensor (PHASE) Exhaust: Cone end shape

Tighten camshaft bracket bolts in four steps in the order shown.
1. Step 1 (bolts 9 - 11): 2.0 N.m (0.2 kg-m, 17 in-lb)
2. Step 2 (bolts 1 - 8): 2.0 N.m (0.2 kg-m, 17 in-lb)
3. Step 3 (bolts 1 - 11): 5.9 N.m (0.6 kg-m, 52 in-lb)
4. Step 4 (bolts 1 - 11): 9.0 - 11.8 N.m (0.92 - 1.2 kg-m, 80 - 104 in-lb)
CAUTION: After tightening camshaft bracket bolts, be sure to wipe off excessive sealant from the parts listed below.
- Mating surface of rocker cover.
- Mating surface of front cover, when installed without the front cover.

Install camshaft sprockets.
- Install them by lining up the mating marks on each camshaft sprocket with the ones painted on the timing chain during removal.
- Before installation of chain tensioner, it is possible to re-match the marks on timing chain with the ones on each sprocket.
CAUTION:
- Aligned mating marks could slip. Therefore, after matching them, hold the timing chain in place by hand.
- Before and after installing chain tensioner, check again to make sure that mating marks have not slipped.

Install chain tensioner.
CAUTION: After installation, pull the stopper pin off completely, and make sure that the tensioner is fully released.
Install chain guide.
Install IVT control (intake valve timing control) cover as follows:
1. Install IVT control solenoid valve to intake valve timing control cover.
2. Install new O-ring to front cover side.
3. Apply Genuine Silicone RTV Sealant to the positions shown in the figure. Refer to RECOMMENDED CHEMICAL PRODUCTS AND SEALANTS .

4. Install IVT control cover bolts in the order shown.
  1. IVT control cover bolts: 12 - 13 N.m (1.2 - 1.4 kg-m, 9 - 10 ft-lb)
Check and adjust valve clearances. Refer to VALVE CLEARANCE .
Installation of the remaining components is in reverse order of removal.
