   INSTALL SPARK PLUG TUBE

   Tip:

   When replacing the cylinder head sub-assembly with a new one, perform the following procedure.

   
   
   1. 

      *a	Protrusion Height
      *b	Paint Mark

      Mark the standard protrusion height from the edge with paint.

      Standard Protrusion Height
      88.7 to 90.2 mm (3.49 to 3.55 in.)

   2. Clean and degrease the spark plug tube holes.

   3. 

      *a	Adhesive 1324

      Apply adhesive to each spark plug tube where it will be pressed into the cylinder head sub-assembly.

      Adhesive
      Toyota Genuine Adhesive 1324, Three Bond 1324 or equivalent

      Note:

      To prevent contamination by foreign matter, install immediately after applying adhesive.

   4. 

      *a	Mark
      *b	Protrusion Height
      *c	Wooden Block
      *d	Press

      Using a press and wooden block, install the 4 spark plug tubes to the specified protrusion height.

      Standard Protrusion Height
      88.7 to 90.2 mm (3.49 to 3.55 in.)

      Note:
      

      • Do not insert to bottom.

      • Do not start the engine within 1 hour after installation.

      • Be careful not to deform the spark plug tube.

      • Ensure that no adhesive drips inside the cylinder head sub-assembly.

   INSTALL VALVE SPRING SEAT

   
   
   1. 

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

   INSTALL VALVE STEM OIL SEAL

   
   
   1. 

      *1	Intake Valve Stem Oil Seal
      *2	Exhaust Valve Stem Oil Seal
      *a	Gray
      *b	Black

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

      Note:

      Pay attention when installing the valve stem oil seals. For example, installing an intake valve stem oil seal onto the exhaust side or installing an exhaust valve stem oil seal onto the intake side can cause installation problems later.

      Tip:

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

   2. 

      *a	Correct
      *b	Incorrect

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

      Note:

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

   INSTALL INTAKE VALVE

   
   
   1. 

      *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. 

      *1	Outer Compression Spring
      *2	Valve Spring Retainer
      *3	Cylinder Head Sub-assembly
      	Upper Side

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

      Note:
      

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

      • Install the same parts to their original positions.

   3. 

      *a	Wooden Block

      Using SST and wooden blocks, compress the outer compression spring and install the 16 valve spring retainer locks.

      Note:

      Install the same parts to their original positions.

   4. 

      *a	Plastic Hammer
      *b	Wooden Block

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

      Note:
      

      • Be careful not to damage the intake valve stem tip.

      • Be careful not to tap the retainer.
