  2. INSTALL NO. 2 STRAIGHT SCREW PLUG


    1. A01WVOEE01

      Using a 14 mm hexagon wrench, install 2 new gaskets and the 2 straight screw plugs.

      Torque:
      85 N*m  { 867 kgf*cm, 63 ft.*lbf }

  3. INSTALL NO. 1 STRAIGHT SCREW PLUG


    1. A01WSEYE01

      Using a 10 mm hexagon wrench, install 6 new gaskets and the 6 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


    1. A01WW37E01
      *1 Intake Side:
      *2 Exhaust Side:
      *3 Gray

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

      Note

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

      Tech Tips

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