CYLINDER HEAD REASSEMBLY

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.

      Torque:
      9.0 N*m  { 92 kgf*cm, 80 in.*lbf }

      *a for Intake Side of Bank 2 *b for Intake Side of Bank 1
      *c for Exhaust Side of Bank 2 *d for Exhaust Side of Bank 1
      *e for Front Side of Bank 2 *f for Front Side of Bank 1

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

  3. INSTALL NO. 1 STRAIGHT SCREW PLUG


    1. Using a 10 mm hexagon wrench, install 6 new gaskets and the 6 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 for Intake Side
      *B for Exhaust Side
      *1 Brown
      *2 Gray

      Apply a light coat of engine oil to 2 new valve stem oil seals.

      Note

      Pay attention when installing the intake and exhaust valve stem oil seals. 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 brown and the exhaust valve oil seals are gray.
