CYLINDER HEAD REASSEMBLY

PROCEDURE


  1. INSTALL SPARK PLUG TUBE

    Tech Tips

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


    1. B006LD2C20
      *a 1.0 to 3.0 mm (0.0394 to 0.118 in.)
      *b 9.0 to 15.0 mm (0.354 to 0.591 in.)

      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.)

      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. B006MSKC12
      *a Cylinder Head Top Surface
      *b 72.9 mm (2.87 in.)

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

      Standard Protrusion Height
      72.9 mm (2.87 in.)

      Note

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

  2. INSTALL NO. 1 STRAIGHT SCREW PLUG


    1. Apply adhesive to the No. 1 straight screw plug.

      Adhesive
      Toyota Genuine Adhesive 1324, Three Bond 1324 or equivalent

      Note

      Install the No. 1 straight screw plug within 3 minutes of applying adhesive.

    2. B006OKLC06
      *A for Bank 1
      *B for Bank 2

      Using a 10 mm hexagon wrench, install 4 new gaskets and the 4 No. 1 straight screw plugs.

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

  3. INSTALL NO. 2 STRAIGHT SCREW PLUG


    1. B006MW0C06
      *A for Bank 1
      *B for Bank 2

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

      Torque:
      80 N*m  { 816 kgf*cm, 59 ft.*lbf }

  4. INSTALL VALVE SPRING SEAT


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

  5. INSTALL INTAKE VALVE STEM OIL SEAL


    1. B006NVLC02
      *a Gray
      *b Black
      *c Intake Side
      *d Exhaust Side

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

      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. B006QZ8C09
      *1 Valve Stem Oil Seal
      *a Correct
      *b Incorrect

      Using SST, push in the intake valve stem oil seal.

      SST
      09201-41020

      Note


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

      • Do not push in the intake valve stem oil seal at an angle.

  6. INSTALL EXHAUST VALVE STEM OIL SEAL

    Tech Tips

    Use the same procedure as for the intake side.

  7. INSTALL EXHAUST VALVE


    1. B006Q9LC01
      *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. Install the exhaust valve, inner 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. B006P1DC01
      *1 Inner Compression Spring
      *2 Valve Spring Retainer
      *3 Cylinder Head Sub-assembly
      *a Up

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

      Note


      • Install the inner compression spring with its tapered side facing upward (towards the valve spring retainer).

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

    4. B006OB7N01

      Using SST, compress the inner compression spring and install the valve spring retainer lock.

      SST

      09202-00020
    5. B006MRL

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

      Note

      Be careful not to damage the retainer.

  8. INSTALL INTAKE VALVE


    1. B006NMIC01
      *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. Install the intake valve, inner 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. B006P1DC01
      *1 Inner Compression Spring
      *2 Valve Spring Retainer
      *3 Cylinder Head Sub-assembly
      *a Up

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

      Note


      • Install the inner compression spring with its tapered side facing upward (towards the valve spring retainer).

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

    4. B006NBSN03

      Using SST, compress the inner compression spring and install the valve spring retainer lock.

      SST
      09202-70020   ( 09202-01010, 09202-01020 )

    5. B006PLM

      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.
