PROCEDURE


  1. INSTALL STUD BOLT

    Note

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


    1. Using E6 and E8 "TORX" sockets, install the stud bolts.

      Torque:
      for bolt A
      10 N*m  { 102 kgf*cm, 7 ft.*lbf }
      for bolt B
      4.0 N*m  { 41 kgf*cm, 35 in.*lbf }

      *C Exhaust Side of RH *D Exhaust Side of LH
      *E Rear Side of RH *F Rear Side of LH

  2. INSTALL NO. 2 STRAIGHT SCREW PLUG


    1. Using a 14 mm hexagon wrench, install 2 new gaskets and the 2 No. 2 straight screw plugs.

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

  3. INSTALL NO. 1 STRAIGHT SCREW PLUG


    1. Using a 10 mm hexagon wrench, install 4 new gaskets and the 4 No. 1 straight screw plugs.

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

  4. INSTALL VALVE SPRING SEAT


    1. Install the valve spring seats to the cylinder head.

  5. INSTALL VALVE STEM OIL SEAL

      *A Intake Side
      *B Exhaust Side
      *1 Gray
      *2 Black

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

      Tech Tips

      The intake valve oil seals are gray and the exhaust valve oil seals are black.

      Note

      Pay attention when installing the intake and exhaust valve stem 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.

  6. INSTALL INTAKE VALVE


    1. A01XF84E01
      *1 30 mm (1.18 in.) or more

      Apply a sufficient coat of engine oil to the tip area of the intake valve shown in the illustration.

    2. Install the intake valve, inner compression spring and valve spring retainer to the cylinder head.

      Note

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

    3. Using SST, compress the inner compression spring and install the 2 valve spring retainer locks.
