  1. INSTALL SPARK PLUG TUBE

    Tech Tips

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


    1. A01G60EE01

      Apply adhesive onto the shaded area of a new spark plug tube.

      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 after applying adhesive.

      • Be careful not to deform the spark plug tube.

      • Be careful not to expose the seal to coolant for at least 1 hour after installing it.

      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 CYLINDER HEAD STUD BOLT


    1. A01G4FOE05

      Using an E7 "TORX" socket wrench, install the 5 cylinder head stud bolts.

      Torque:
      9.0 N*m  { 92 kgf*cm, 80 in.*lbf }

  3. INSTALL NO. 1 STRAIGHT SCREW PLUG


    1. A01G74B

      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. A01G9G8

      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 valve spring seats to the cylinder head sub-assembly.

  6. INSTALL VALVE STEM OIL SEAL

      *a Intake
      *b Exhaust
      *c Mark "NOK"
      *d Gray
      *e Black

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

      Note

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

      Tech Tips

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

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

    2. Install the intake 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. A01G7T5E01

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

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

    2. Install the exhaust 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. A01G78ME01

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

      SST
