  1. INSTALL SPARK PLUG TUBE

    Tech Tips

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


    1. B000IW8E01

      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
      2.0 mm (0.0787 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. B000LAZE01

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

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

  3. INSTALL NO. 1 STRAIGHT SCREW PLUG


    1. B000JU2

      Using a 10 mm hexagon wrench, install 3 new gaskets and the 3 straight screw plugs.

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

  4. INSTALL NO. 2 STRAIGHT SCREW PLUG


    1. B000N0Q

      Using a 14 mm hexagon wrench, install a new gasket and the 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.

  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 oil seals.

      Note

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

      Tech Tips

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

      Note

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

  7. INSTALL INTAKE VALVE

    Tech Tips

    Type A and Type B can be distinguished by the shape of the compression spring.
