      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. A000ZI5E02
      *1 Intake Side:

      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 to 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.

    2. A000X6VE01
      *1 Narrow
      *2 Wide

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

      Note
