    INSTALL SPARK PLUG TUBE

    Tip:

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


    1. A01UEDMC18
      *a Adhesive
      *b Application Width
      *c Distance

      Apply adhesive to a new spark plug tube as shown in the illustration.

      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.)
      Distance
      1.0 to 7.0 mm (0.0394 to 0.276 in.)
      Note:

      • Install the spark plug tube within 3 minutes of applying adhesive.

      • Be careful not to deform the spark plug tube.

      • Do not expose the spark plug tube to engine oil for at least 1 hour after installing it.

    2. A01UCWAC16
      *a Protrusion Height

      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.

    INSTALL VALVE SPRING SEAT


    1. Install the valve spring seat to the cylinder head sub-assembly.

  6. Click here

    INSTALL VALVE STEM OIL SEAL


    1. A01UDNNC11
      *a Intake Valve Stem Oil Seal
      *b Exhaust Valve Stem Oil Seal
      *c "NOK" Mark
      *d Gray
      *e Black

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

      Note:

      Make sure to install each valve stem oil seal to the correct side. Installing an intake valve stem oil seal to the exhaust side or installing an exhaust valve stem oil seal to 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. A01UEL5C07
      *a Correct
      *b Incorrect

      Using SST, push in the valve stem oil seal.

      09201-41020
      Note:

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