PROCEDURE


  1. INSTALL STUD BOLT

    Note

    If a stud bolt is deformed or its threads are damaged, replace it.


    1. Using E7 and E8 "TORX" socket wrenches, install the stud bolts.

      A01HK4KC03
      *a Intake Manifold Side *b Exhaust Manifold Side
      *c 24 mm (0.945 in.) *d 13 mm (0.512 in.)
      *e 45 mm (1.772 in.) *f 20 mm (0.787 in.)
      *g 35 mm (1.378 in.) - -
      Torque:
      9.5 N*m  { 97 kgf*cm, 84 in.*lbf }

  2. INSTALL NO. 2 STRAIGHT SCREW PLUG

    Note

    If coolant leaks from the No. 2 straight screw plug or the plug is corroded, replace it.


    1. Using a 10 mm hexagon wrench, install 3 new gaskets and the 3 No. 2 straight screw plugs.

      Torque:
      44 N*m  { 449 kgf*cm, 32 ft.*lbf }

  3. INSTALL VALVE SPRING SEAT


    1. Install the valve spring seats to the cylinder head sub-assembly.

  4. INSTALL VALVE STEM OIL SEAL


    1. A01HJZ6C28
      *a Intake Side
      *b Exhaust Side
      *c Gray
      *d Black

      Apply a light coat of engine oil to new valve stem oil seals.

      Note

      Pay close attention when installing the intake and exhaust valve oil seals. For example, installing the intake valve stem oil seal to the exhaust side or installing the exhaust valve stem oil seal to the intake side can cause installation problems later.

      Tech Tips

      The intake side valve stem oil seal is gray and the exhaust side valve stem oil seal is black.

    2. A01HFTZC09
      *a CORRECT
      *b INCORRECT

      Using SST, push in the valve stem oil seals.

      Note

      Failure to use SST will cause the valve stem oil seal to be damaged or improperly seated.

  5. INSTALL INTAKE VALVE


    1. A01HFK7C02
      *a 30 mm (1.18 in.) or more

      Apply plenty of engine oil to the tip area of the intake valve shown in the illustration.

    2. A01HEPUC03
      *a Narrow
      *b Wide

      Install the intake valve, compression spring and valve spring retainer to the cylinder head sub-assembly.

      Note

      Install the same parts in the same combination to their original locations.

    3. A01HH97N01

      Using SST and wooden blocks, compress the compression spring and install the valve spring retainer locks.

      09202-70020
      09202-00021

    4. Using a plastic-faced hammer, lightly tap the valve stem tip to ensure a proper fit.

      Note


      • Be careful not to damage the valve stem tip.

      • Be careful not to damage the valve spring retainer.

  6. INSTALL EXHAUST VALVE


    1. A01HDY2C01
      *a 30 mm (1.18 in.) or more

      Apply plenty of engine oil to the tip area of the exhaust valve shown in the illustration.

    2. A01HJ2AC03
      *a Narrow
      *b Wide

      Install the exhaust valve, compression spring and valve spring retainer to the cylinder head sub-assembly.

      Note

      Install the same parts in the same combination to their original locations.

    3. A01HEGIN01

      Using SST and wooden blocks, compress the compression spring and install the valve spring retainer locks.

      SST
      09202-70020
      09202-00021

    4. Using a plastic-faced hammer, lightly tap the valve stem tip to ensure a proper fit.

      Note


      • Be careful not to damage the valve stem tip.

      • Be careful not to damage the valve spring retainer.
