      Using a wooden block and hammer, tap in the spark plug tube to the specified protrusion height.

      Standard protrusion height
      72.9 mm (2.87 in.)

      Note

      To avoid tapping in the spark plug tube too far, measure the protrusion height while tapping it.

  2. INSTALL NO. 1 STRAIGHT PLUG


    1. Apply adhesive to the No. 1 straight plug of the cylinder head.

  6. INSTALL STUD BOLT

    Note

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


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

      10 N*m  { 102 kgf*cm, 7 ft.*lbf }
      for stud bolt C
      4.0 N*m  { 41 kgf*cm, 35 in.*lbf }

  7. INSTALL VALVE SPRING SEAT


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

  8. INSTALL VALVE STEM OIL SEAL

      Text in Illustration
      *1 Gray
      *2 Black
      *a Intake Side
      *b Exhaust Side

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

      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.

      Tech Tips

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