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
  
  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.
INSTALL CYLINDER HEAD STUD BOLT
1. Using an E7 "TORX" socket wrench, install the cylinder head stud bolts.

  Torque:
  
  44 N*m { 449 kgf*cm, 32 ft.*lbf }
INSTALL NO. 2 STRAIGHT SCREW PLUG
1. 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 }
INSTALL VALVE SPRING SEAT

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

for Intake Side

The intake side valve stem oil seals is gray or black.
