PROCEDURE


  1. INSTALL SPARK PLUG TUBE

    Tech Tips

    When using a new cylinder head sub-assembly, the spark plug tubes must be replaced.


    1. B004MBAC18
      *a Adhesive
      *b Application Width
      *c Distance

      Apply adhesive to a new spark plug tube as shown in the illustration.

      Adhesive
      Toyota Genuine Adhesive 1324, Three Bond 1324 or equivalent
      Standard Application Width
      1.0 to 3.0 mm (0.0394 to 0.118 in.)
      Distance
      1.0 to 7.0 mm (0.0394 to 0.276 in.)

      Note


      • Install the spark plug tube within 3 minutes of applying adhesive.

      • Be careful not to deform the spark plug tube.

      • Do not expose the spark plug tube to engine oil for at least 1 hour after installing it.

    2. B004L7XC16
      *a Protrusion Height

      Using a wooden block and hammer, tap in the spark plug tube to the specified protrusion height.

      Standard Protrusion Height
      112 mm (4.41 in.)

      Note

      To avoid tapping in the spark plug tube too far, measure the protrusion height while tapping it.

  2. INSTALL STUD BOLT


    1. B004LP3C01
      *A Type A
      *B Type B
      *a 18 mm (0.709 in.)
      *b 33 mm (1.30 in.)
      *c 13 mm (0.512 in.)
      *d 20 mm (0.787 in.)
      *e 35 mm (1.38 in.)

      Using an E7 or E8 "TORX" socket wrench, install the 5 stud bolts.

      Torque:
      6.5 N*m  { 66 kgf*cm, 58 in.*lbf }

  3. INSTALL NO. 1 STRAIGHT SCREW PLUG


    1. B006XGM

      Using a 10 mm hexagon wrench, install 3 new gaskets and the 3 No. 1 straight screw plugs.

      Torque:
      44 N*m  { 449 kgf*cm, 32 ft.*lbf }

  4. INSTALL NO. 2 STRAIGHT SCREW PLUG


    1. B006ZRY

      Using a 14 mm hexagon wrench, install a new gasket and the No. 2 straight screw plug.

      Torque:
      78 N*m  { 795 kgf*cm, 58 ft.*lbf }

  5. INSTALL VALVE SPRING SEAT


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

  6. INSTALL VALVE STEM OIL SEAL


    1. B004M5OC11
      *a Intake Valve Stem Oil Seal
      *b Exhaust Valve Stem Oil Seal
      *c "NOK" Mark
      *d Gray
      *e Black

      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 gray and the exhaust valve stem oil seals are black.

    2. B004KI5C07
      *a Correct
      *b Incorrect

      Using SST, push in the 8 intake valve stem oil seals and 8 exhaust valve stem oil seals.

      SST
      09201-41020

      Note

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

  7. INSTALL INTAKE VALVE


    1. B004INWC03
      *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. B004NKRC01
      *a Narrow
      *b Wide

      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.

    3. B004K22N01

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

      SST
      09202-00021
      09202-70020   ( 09202-01010, 09202-01020 )
    4. B004O60

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

      Note

      Be careful not to damage the valve spring retainer.

  8. INSTALL EXHAUST VALVE


    1. B004INWC03
      *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. B004KN0C01
      *a Narrow
      *b Wide

      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.

    3. B004HKLN03

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

      SST
      09202-00021
      09202-70020   ( 09202-01010, 09202-01020 )
    4. B004IH5

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

      Note

      Be careful not to damage the valve spring retainer.
