CYLINDER HEAD REASSEMBLY

CAUTION / NOTICE / HINT

PROCEDURE


  1. INSTALL STUD BOLT

    Note

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


    1. Using E8 and E10 "TORX" socket wrenches, install the 9 stud bolts.

      *a Intake Manifold Side *b Exhaust Manifold Side
      *c 26 mm (1.02 in.) *d 16.7 mm (0.657 in.)
      *e 51.7 mm (2.04 in.) *f 23 mm (0.906 in.)
      *g 15 mm (0.591 in.) *h 40 mm (1.57 in.)
      *i 26.5 mm (1.04 in.) *j 20 mm (0.787 in.)
      *k 50 mm (1.97 in.) - -
      Torque:
      Stud Bolt (A)
      9.0 N*m  { 92 kgf*cm, 80 in.*lbf }
      Stud Bolt (B), (C)
      22 N*m  { 224 kgf*cm, 16 ft.*lbf }

  2. INSTALL NO. 1 STRAIGHT SCREW PLUG

    Note

    If coolant leaks from a No. 1 straight screw plug or the plug is corroded, replace it.


    1. Using a 14 mm hexagon socket wrench, install 6 new gaskets and the 6 No. 1 straight screw plugs.

      Torque:
      135 N*m  { 1377 kgf*cm, 100 ft.*lbf }

  3. INSTALL VALVE SPRING SEAT


    1. Install the 16 valve spring seats to the cylinder head sub-assembly.

  4. INSTALL VALVE STEM OIL SEAL


    1. B005OGIC02
      *a Intake Valve Stem Oil Seal
      *b Exhaust Valve Stem Oil Seal
      *c Brown
      *d Gray
      *e "NOK" Mark

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

      Note

      Make sure to install each valve stem oil seal to the correct side. Installing an intake valve stem oil seal to the exhaust side or installing an exhaust valve stem oil seal to the intake side can cause installation problems later.

      Tech Tips

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

    2. B005PG1C02
      *a Correct
      *b Incorrect

      Using SST, push in the 16 valve stem oil seals.

      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. B005LIUC02
      *a 30 mm (1.18 in.) or more

      Sufficiently apply engine oil to the tip area of the intake valve shown in the illustration.

    2. B005ND3C01
      *a Identification Color (White)
      B005NIZ Upper Side

      Install the 8 intake valves, 8 compression springs and 8 valve spring retainers to the cylinder head sub-assembly.

      Note


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

      • The compression spring has a different identification color for the intake side and exhaust side.

        Make sure to check the color before installation.

    3. B005MNCN01

      Using SST, compress the 8 compression springs and install the 8 valve spring retainer locks.

      SST
      09202-70020   ( 09202-00010, 09202-01010 )
      09202-00021

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

      Note

      Be careful not to damage the valve spring retainer.

  6. INSTALL EXHAUST VALVE


    1. B005LZCC02
      *a 30 mm (1.18 in.) or more

      Sufficiently apply engine oil to the tip area of the exhaust valve shown in the illustration.

    2. B005ND3C01
      *a Identification Color (Purple)
      B005NIZ Upper Side

      Install the 8 exhaust valves, 8 compression springs and 8 valve spring retainers to the cylinder head sub-assembly.

      Note


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

      • The compression spring has a different identification color for the intake side and exhaust side.

        Make sure to check the color before installation.

    3. B005LE9N01

      Using SST, compress the compression spring and install the 8 valve spring retainer locks.

      SST
      09202-70020   ( 09202-00010, 09202-01010 )
      09202-00021

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

      Note

      Be careful not to damage the valve spring retainer.
