      Make sure of the marks and numbers on the camshaft bearing caps and place them in each proper position and direction.

    3. A01W3YEE08

      Temporarily tighten the 8 bolts in the order shown in the illustration.

      Torque:

      Seal packing diameter

      (3.5 to 4.5 mm)

      Apply seal packing in a continuous line as shown in the illustration.

      Seal packing
      Toyota Genuine Seal Packing Black, Three Bond 1207B or equivalent
      Standard 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.

      • Do not start the engine for at least 2 hours after installing.

      Install the camshaft housing sub-assembly LH and tighten the 13 bolts in the order shown in the illustration.

      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, valve contact with a piston at TDC 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.
