Exhaust manifold sub-assembly RH x Cylinder head sub-assembly RH 21 Nm (214 Kgf-cm, 15 ft-lbf)
Exhaust manifold sub-assembly LH x Cylinder head sub-assembly LH 21 Nm (214 Kgf-cm, 15 ft-lbf)
Intake manifold x Cylinder head sub-assembly 21 Nm (214 kgf-cm, 15 ft-lbf)
Camshaft bearing cap RH x Camshaft housing RH
- Temporarily tighten the 8 bolts in the order shown in the illustration.
Torque: 10 Nm (102 kgf-cm, 7ft-lbf)
RH:
- Install the camshaft housing RH and tighten the 12 bolts in the order shown in the illustration.
Torque: 28 Nm (286 kgf-cm, 21ft-lbf)
- When installing the camshaft housing RH, it is necessary to correctly position the camshafts as shown in the illustration. Failure to correctly position these parts may result in damage due to contact between the pistons and valves. If a camshaft is rotated with a piston at TDC, valve contact will occur.
- If any of the bolts are loosened during installation, remove the camshaft housing, clean the installation surfaces, and reapply seal packing.
- If the camshaft housing is removed because any of the bolts are loosened during installation, make sure that the previously applied seal packing does not enter any oil passages.
- Tighten the 8 bolts in the order shown in the illustration.
Torque: 16 Nm (163 kgf-cm, 12ft-lbf)
