CYLINDER HEAD REASSEMBLY


  1. INSTALL SPARK PLUG TUBE

    Note

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


    1. A0040TAE11

      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 of 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 the tube.

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

      Standard protrusion height
      122 mm (4.80 in.)

      Note

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

  2. INSTALL STUD BOLT

    Note

    If a stud bolt is deformed or its threads are damaged, replace it.


    1. Using an E8 "TORX" socket, install the stud bolts.

  3. INSTALL NO. 2 STRAIGHT SCREW PLUG

    Note

    If water leaks from the straight screw plug or the plug is corroded, replace it.


    1. A0041GB

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

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

  4. INSTALL VALVE SPRING SEAT


    1. Install the valve spring seats to the cylinder head.

  5. INSTALL VALVE STEM OIL SEAL

      *c Gray
      *d Black

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

      Note

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

      Tech Tips

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