CAMSHAFT BEARING CAP (for Bank 1)

Temporarily tighten the 8 bolts in the order shown in the illustration.
mTorque: 10 Nm (102 kgf-cm, 7 ft-lbf)

CAMSHAFT HOUSING SUB-ASSEMBLY RH

Install the camshaft housing RH and tighten the 12 bolts in the order shown in the illustration.
Torque: 28 Nm (286 kgf-cm, 21 ft-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.
