    INSTALL SPARK PLUG TUBE

    Note:

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


    1. A003YCWE05

      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.

    2. A003ZIJE04

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

      Table 1. Text in Illustration
      *a Cylinder Head Casting Surface
      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.

    INSTALL VALVE STEM OIL SEAL


    1. A003WQPE08

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

      Table 3. Text in Illustration
      *a Intake Side:
      *b Exhaust Side:
      *c Gray
      *d Black
      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.

      Tip:

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

    2. A003X35E02

      Using SST, push on the oil seal.
