Repair Procedure: Reassembly Steps 1 - 12
1. Install the spark plugs.Torque: 25 N-m (255 kgf-cm, 18 ft-lbf)
2. Install the valve stem caps.
3. Install the valve rocker arms.
4. Install the No. 3 camshaft.
A. Align the mark plate (yellow) of the No. 2 chain with the timing marks of the camshaft timing gear assembly as shown.
B. Clean the camshaft journals and apply engine oil.
C. Make sure that the valve rocker arms are installed with the lash adjuster and valve stem cap properly as shown.
D. Temporarily put the timing chain to the No. 3 camshaft on the camshaft timing gear assembly and place the No. 3 camshaft on the camshaft housing LH.
NOTE
- Temporarily put the timing chain on the camshaft timing gear assembly without installing to the sprocket.
- Place the camshaft with the timing mark faces on the top.
5. Install the No. 1 camshaft using the same procedure as step 4.
6. Install the No. 4 camshaft.
A. Clean the camshaft journals and apply engine oil to them.
B. Hold the No. 2 chain and slide the No. 4 camshaft in from the front of the vehicle.
C. Align the mark plate (yellow) with the timing marks of the camshaft timing exhaust gear LH.
D. Hold the No. 2 chain and install the No. 3 chain tensioner assembly.
Torque: 21 N-m (214 kgf-cm, 15 ft-lbf)
7. Install the No. 2 camshaft using the same procedure as step 6.
Degrease and dry the bearing cap bolts and holes before reinstallation.
If you install oily bolts you will overtighten and stretch them due to the decreased friction.
8. Install the camshaft bearing cap.
A. LH bank:
(1) Clean the camshaft bearing caps and apply engine oil.
(2) Make sure that the valve rocker arms are installed with the lash adjuster and valve stem cap properly.
(3) Make sure of the marks and numbers on the camshaft bearing caps and temporarily tighten the 16 bolts.
(4) Tighten the 8 M6 bolts in the sequence shown.
Torque: 10 N-m (102 kgf-cm, 7 ft-lbf)
(5) Tighten the 8 M8 bolts in the sequence shown.
Torque: 28 N-m (286 kgf-cm, 21 ft-lbf)
(6) Tighten the 8 M6 bolts to their final torque value in the sequence shown in Figure 61.
Torque: 16 N-m (163 kgf-cm, 12 ft-lbf)
B. RH bank:
(1) Clean the camshaft bearing caps and apply engine oil.
(2) Make sure that the valve rocker arms are installed with the lash adjuster and valve stem cap properly.
(3) Make sure of the marks and numbers on the camshaft bearing caps and temporarily tighten the 16 bolts.
(4) Tighten the 9 M6 bolts in the sequence shown.
Torque: 10 N-m (102 kgf-cm, 7 ft-lbf)
(5) Tighten the 9 M8 bolts in the sequence shown.
Torque: 28 N-m (286 kgf-cm, 21 ft-lbf)
(6) Tighten the 9 M6 bolts to their final torque value in the sequence shown in Figure 64.
Torque: 16 N-m (163 kgf-cm, 12 ft-lbf)
9. Install the timing chain.
A. LH bank:
Align the mark plate (yellow) of the timing chain with the timing marks of the camshaft timing gear assembly and install to the sprocket.
NOTE
If the paint mark is NOT aligned, turn the crankshaft slightly to adjust the position.
B. RH bank:
(1) Align the mark plate (yellow) of the timing chain with the timing marks of the camshaft timing gear assembly and install to the sprocket.
NOTE
If the paint mark is NOT aligned, turn the crankshaft and adjust one notch each as shown in the illustration.
(2) Set the No. 1 cylinder to TDC/compression, by aligning the timing mark to 0° on the timing chain cover by rotating the crankshaft counterclockwise.
(3) Slightly turn the crankshaft and loosen tension for the timing chain where the No. 1 chain tensioner is attached.
10. Install the No. 1 chain tensioner assembly.
A. Move the stopper plate upward to release the lock, and push the plunger deep into the tensioner.
B. Move the stopper plate downward to set the lock, and insert a hexagon wrench into the hole of the stopper plate.
C. Install the No. 1 chain tensioner assembly with the 2 bolts.
Torque: 10 N-m (102 kgf-cm, 7 ft-lbf)
D. Remove the lock pin of the No. 1 chain tensioner assembly. Check that each timing mark is aligned with the crankshaft at the TDC/compression.
E. Turn the crankshaft 2 rotations and double-check that each timing mark is positioned properly.
11. Install the NEW gasket and the timing chain cover plate with the 4 bolts.
Torque: 9 N-m (93 kgf-cm, 7 ft-lbf)
12. Install the injector driver with the bolt and 2 nuts.
Torque: 10 N-m (102 kgf-cm, 7 ft-lbf)
