    1. A01SES2

      Turn the crankshaft pulley and align its groove with the "0" timing mark of the timing chain cover sub-assembly.

    2. Check that the timing marks of the camshaft timing gears are aligned with the timing marks of the bearing cap as shown in the illustration.

      If not, turn the crankshaft 1 complete revolution (360°) and align the timing marks as above.

  6. INSPECT VALVE CLEARANCE


    1. Using a feeler gauge, measure the valve clearance indicated in the illustration.

      Intake Side 0.15 to 0.25 mm (0.00591 to 0.00984 in.)
      Exhaust Side 0.29 to 0.39 mm (0.0114 to 0.0154 in.)

      Record the out-of-specification valve clearance measurements. They will be used later to determine the required replacement valve lifter.

    2. Turn the crankshaft 2/3 of a revolution (240°).

    3. Using a feeler gauge, measure the valve clearance indicated in the illustration.

      Exhaust Side 0.29 to 0.39 mm (0.0114 to 0.0154 in.)

      Record the out-of-specification valve clearance measurements. They will be used later to determine the required replacement valve lifter.

    4. Turn the crankshaft 2/3 of a revolution (240°).

      Intake Side 0.15 to 0.25 mm (0.00591 to 0.00984 in.)
      Exhaust Side 0.29 to 0.39 mm (0.0114 to 0.0154 in.)

      Record the out-of-specification valve clearance measurements. They will be used later to determine the required replacement valve lifter.

  7. ADJUST VALVE CLEARANCE


    1. Remove the camshafts.

    2. Remove the 24 valve lifters from the cylinder head LH and RH.

    3. A01LAS4

      Determine the size of the valve lifter to be installed according to the following formulas and charts.


      1. Using a micrometer, measure the thickness of the removed valve lifter.

      2. Calculate the thickness of a new valve lifter so that the valve clearance comes within the specified range.

        T
        Thickness of removed valve lifter
        A
        Measured valve clearance
        N
        Thickness of new valve lifter
        Intake
        N = T + (A - 0.20 mm (0.00787 in.))
        Exhaust
        N = T + (A - 0.34 mm (0.0134 in.))

      3. Select a new valve lifter with a thickness as close as possible to the calculated value.

        Tech Tips

        Lifters are available in 35 sizes in increments of 0.020 mm (0.000787 in.), from 5.060 mm (0.1992 in.) to 5.740 mm (0.2260 in.).

        EXAMPLE:

        A 5.250 mm (0.2067 in.) lifter is installed and the measured clearance is 0.400 mm (0.0157 in.). Replace the 5.250 mm (0.2067 in.) lifter with a No. 46 lifter.
