    2. Apply seal packing in a continuous line as shown below.

      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.) 

      NOTE:
      • 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.

    3. Install the camshaft housing sub-assembly RH and tighten the 12 bolts in the order shown below.

      Torque: 28 N*m (286 kgf*cm, 21 ft.*lbf) 

      NOTE:
      • When installing the camshaft housing RH, it is necessary to correctly position the camshafts as shown below.

        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 sub-assembly 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.
