PROCEDURE


  1. REMOVE CYLINDER HEAD COVER SUB-ASSEMBLY

  2. SET NO. 1 CYLINDER TO TDC/COMPRESSION


    1. B002655C01
      *a Matchmark

      Align the matchmarks of the crankshaft pulley and timing gear cover by rotating the crankshaft clockwise.

      Tech Tips

      Make sure that both cam lobes (intake side and exhaust side) of the No. 1 cylinder face upward.

  3. INSPECT VALVE CLEARANCE


    1. B0027M7C01
      *a Front
      *b Exhaust
      *c Intake

      Check only the valves indicated.


      1. Using a feeler gauge, measure the clearance between the valve lifter and camshaft sub-assembly.

        Standard Valve Clearance (Cold)
        Item Specified Condition
        Intake 0.2 to 0.3 mm (0.00787 to 0.0118 in.)
        Exhaust 0.35 to 0.45 mm (0.0138 to 0.0177 in.)

        Write down any valve clearance measurements that are not within the specified range. These measurements will be used later to determine the size of the adjustment valve lifter to be installed.

    2. Turn the crankshaft 360° to set the No. 4 cylinder to TDC/compression.

    3. B0025P0C01
      *a Front
      *b Exhaust
      *c Intake

      Check only the valves indicated.


      1. Using a feeler gauge, measure the clearance between the valve lifter and camshaft sub-assembly.

        Standard Valve Clearance (Cold)
        Item Specified Condition
        Intake 0.2 to 0.3 mm (0.00787 to 0.0118 in.)
        Exhaust 0.35 to 0.45 mm (0.0138 to 0.0177 in.)

        Write down any valve clearance measurements that are not within the specified range. These measurements will be used later to determine the size of the adjustment valve lifter to be installed.

  4. ADJUST VALVE CLEARANCE


    1. Remove the camshaft sub-assemblies.

    2. Remove the valve lifters.

    3. B0025YJ

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

    4. Calculate the thickness of a new lifter so that the valve clearance is within the specified range.

      A B C
      New valve lifter thickness Used valve lifter thickness Measured valve clearance
      New valve lifter thickness
      Intake: A = B + (C - 0.25 mm (0.00984 in.))
      Exhaust: A = B + (C - 0.40 mm (0.0157 in.))

    5. Select a new valve lifter with a thickness as close as possible to the calculated values.

      Tech Tips

      Valve lifters are available in 35 sizes in increments of 0.02 mm (0.000787 in.), from 5.06 mm (0.199 in.) to 5.74 mm (0.226 in.).

    6. Install the selected valve lifter.
