(a) Make sure that the valve rocker arm is installed as
shown in the illustration.

the illustration.
Seal packing:
Toyota Genuine Seal Packing Black, Three
Bond 1207B or equivalent
Seal diameter:
3.5 to 4.5 mm (0.138 to 0.177 in.)
NOTICE:
• Remove any oil from the contact surface.
• Install the camshaft housing sub-assembly
RH within 3 minutes.
• Do not start the engine for at least 2 hours
after installing.
(c) Install the camshaft housing RH and tighten the 12
bolts in the order shown in the illustration.
Torque: 28 N*m (286 kgf*cm, 21 ft.*lbf)
NOTICE:
• 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.
