CYLINDER HEAD REASSEMBLY

PROCEDURE


  1. INSTALL STUD BOLT

    Note

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


    1. Using an E6 "TORX" socket wrench, install the stud bolts labeled A to the cylinder head sub-assembly.

      Torque:
      for stud bolt A
      6.0 N*m  { 61 kgf*cm, 53 in.*lbf }

    2. Install the stud bolts labeled B to the cylinder head sub-assembly.

      Torque:
      for stud bolt B
      10 N*m  { 102 kgf*cm, 7 ft.*lbf }

    3. Using an E10 "TORX" socket wrench, install the stud bolts labeled C and D to the cylinder head sub-assembly.

      Torque:
      for stud bolt C
      19 N*m  { 194 kgf*cm, 14 ft.*lbf }
      for stud bolt D
      20 N*m  { 204 kgf*cm, 15 ft.*lbf }

      *a Cylinder Head Cover Sub-assembly Side *b Exhaust Manifold Side
      *c Intake Manifold Side *d 12 mm (0.472 in.)
      *e 37 mm (1.46 in.) *f 34 mm (1.34 in.)
      *g 23 mm (0.906 in.) *h 15 mm (0.591 in.)
      *i 25 mm (0.984 in.) *j 65 mm (2.56 in.)
      *k 40 mm (1.57 in.) - -

  2. INSTALL NO. 1 STRAIGHT SCREW PLUG WITH HEAD


    1. Using a 6 mm hexagon wrench, install 4 new No. 1 straight screw plug with heads to the cylinder head sub-assembly.

      Torque:
      25 N*m  { 255 kgf*cm, 18 ft.*lbf }

  3. INSTALL VALVE SPRING SEAT


    1. Install the valve spring seats to the cylinder head sub-assembly.

  4. INSTALL VALVE STEM OIL SEAL


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

    2. B003R7TC01
      *1 Valve Stem Oil Seal
      *a CORRECT
      *b INCORRECT

      Using SST, push in the intake valve stem oil seals and exhaust valve stem oil seals to the valve guide bush.

      SST
      09201-41020

      Note

      Failure to use SST will cause the valve stem oil seal to be damaged or improperly seated.

  5. INSTALL INTAKE VALVE


    1. B003SD0C01
      *a 30 mm (1.18 in.) or more

      Apply plenty of engine oil to the tip area of the intake valve shown in the illustration.

    2. Install the intake valve, valve compression spring and valve spring retainer to the cylinder head sub-assembly.

      Note

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

    3. B003M4IN01

      Using SST and wooden blocks, compress the valve compression spring and install the valve spring retainer locks to the valve spring retainer.

      SST
      09202-70020
      09202-00021

    4. Using a plastic-faced hammer, lightly tap the intake valve stem tip to ensure a proper fit.

      Note

      Be careful not to damage the valve spring retainer.

  6. INSTALL EXHAUST VALVE


    1. B003OW7C01
      *a 30 mm (1.18 in.) or more

      Apply plenty of engine oil to the tip area of the exhaust valve shown in the illustration.

    2. Install the exhaust valve, valve compression spring and valve spring retainer to the cylinder head sub-assembly.

      Note

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

    3. B003MDZN01

      Using SST and wooden blocks, compress the valve compression spring and install the valve spring retainer locks to the valve spring retainer.

      SST
      09202-70020
      09202-00021

    4. Using a plastic-faced hammer, lightly tap the exhaust valve stem tip to ensure a proper fit.

      Note

      Be careful not to damage the valve spring retainer.

  7. INSTALL VALVE STEM CAP


    1. Apply a light coat of engine oil to the valve stem caps.

    2. Install the 16 valve stem caps to the cylinder head sub-assembly.

      Note


      • Install the valve stem cap at the same place it was removed from.

      • Do not drop the valve stem caps into the cylinder head sub-assembly.
