  1. INSTALL SPARK PLUG TUBE

    Tech Tips

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

    1. 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 engine oil for at least 1 hour after installing it.

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

      72.9 mm (2.87 in.)

      Note

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

  2. INSTALL NO. 1 STRAIGHT SCREW PLUG

    1. Using a 10 mm hexagon wrench, install 4 new gaskets and the 4 No. 1 straight screw plugs.

  4. INSTALL VALVE SPRING SEAT

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

  5. INSTALL VALVE STEM OIL SEAL

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

      Black

      (Exhaust Side)

      Note

      Pay attention when installing the intake and exhaust valve stem oil seals. For example, installing the intake valve stem oil seal into the exhaust side or installing the exhaust valve stem oil seal to 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.

    2. Using SST, push in the oil seals.

      Note

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

  6. INSTALL EXHAUST VALVE

    1. Apply a sufficient coat of engine oil to the tip area of the exhaust valve shown in the illustration.

    2. Install the exhaust valve, inner compression spring and valve spring retainer to the cylinder head.

      Note

      Install the same parts in the same combination to the original locations.

    3. Using SST, compress the inner compression spring and install the 2 valve spring retainer locks.
