    3. A005KI8

      Using a plastic-faced hammer and the valve stem of another valve (not in use) with its tip wrapped in tape, gently tap the valve stem tip to ensure a proper fit.

      Note

      Do not damage the valve stem tip.

  5. INSTALL EXHAUST VALVE


    1. Install the valve, valve spring seat, valve spring, and retainer.

    2. Using SST, compress the valve spring and place the 2 retainer locks around the valve stem.

      SST
      09202-70020   ( 09202-00010 )

    3. Using a pin-punch (5mm) and the valve stem (not in use) with the tip wrapped in tape, lightly tap the valve stem tip to ensure a proper fit.

      Note

      Do not damage the valve stem tip.

  6. INSTALL VALVE STEM CAP


    1. Apply a light coat of engine oil to the valve stem caps.

    2. Install the 16 valve stem caps.

      Note

      Install the valve stem caps to their original locations in the original order.

  7. INSTALL CYLINDER HEAD OIL NOZZLE


    1. Install the cylinder head oil nozzle.

      Torque:
      7.0 N*m  { 71 kgf*cm, 62 in.*lbf }

  8. INSTALL OIL CONTROL VALVE FILTER


    1. Make sure that the mesh of the oil control valve filter is free of dirt or foreign matter.

    2. Install the oil control valve filter.

  9. INSTALL NO. 2 WITH HEAD TAPER SCREW PLUG

    A005LVU

    1. Using an 8 mm hexagon wrench, install the No.2 head taper screw plug and a new gasket.

      Torque:
      30 N*m  { 306 kgf*cm, 22 ft.*lbf }

  10. INSTALL NO. 1 WITH HEAD TAPER SCREW PLUG

    A005GON

    1. Using a 10 mm socket hexagon wrench, install the No. 1 with head taper screw plug with a new gasket.

      Torque:
      80 N*m  { 816 kgf*cm, 59 ft.*lbf }

  11. INSTALL VALVE LASH ADJUSTER ASSEMBLY

    Note


    • Keep the valve lash adjuster free of dirt and foreign matter.

    • Only use clean engine oil.


    1. Place the lash adjuster into a container filled with engine oil.

    2. A005L2AE03
      Text in Illustration
      *1 Plunger
      *2 Check Ball
      *3 Low Pressure Chamber
      *4 High Pressure Chamber
      *a Correct
      *b Incorrect
      *c Taper Part

      Insert the tip of SST into the lash adjuster plunger and use the tip to press down on the check ball inside the plunger.

      SST
      09276-75010

    3. Squeeze SST and the lash adjuster together to move the plunger up and down 5 to 6 times.

    4. Check the movement of the plunger and bleed it.

      OK
      Plunger moves up and down.

      Note

      When bleeding air from the high-pressure chamber, make sure that the tip of SST is actually pressing the check ball as shown in the illustration. If the check ball is not pressed, the high-pressure chamber will not be bled.

    5. After bleeding, remove SST. Then, try to press the plunger quickly and firmly with a finger.

      OK
      Plunger is very difficult to move.

      If the result is not as specified, replace the valve lash adjuster assembly.

    6. Install the valve lash adjuster assemblies.

      Note

      Install the lash adjusters to the their original locations.

  12. INSTALL NO. 1 VALVE ROCKER ARM SUB-ASSEMBLY


    1. Apply engine oil to the lash adjuster tips and valve stem cap ends.
