      *a Seal packing diameter
      (3.5 to 4.5 mm)

      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 LH within 3 minutes and tighten the bolts within 15 minutes after applying seal packing.
      • Do not start the engine for at least 2 hours after installing.

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

      NOTE:
      • When installing the camshaft housing sub-assembly LH, 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 sub-assembly LH, clean the installation surfaces, and reapply seal packing.
      • If the camshaft housing sub-assembly LH 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.
    4. Tighten the 8 bolts in the order shown in the illustration.
