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.
-
*a Protrusion Height *b Cylinder Head LH Top Surface Using a hammer and wooden block, tap in the 3 spark plug tubes to the specified protrusion height.
Standard Protrusion Height 75.1 to 76.1 mm (2.96 to 3.00 in.) Note
-
Do not tap in the spark plug tube more than specified.
-
Do not start the engine for at least 1 hour after installation.
-
Be careful not to deform the spark plug tubes.
-
Be careful not to let adhesive drip into the cylinder head LH.
-
-
-
INSTALL NO. 1 STRAIGHT SCREW PLUG
-
Apply adhesive to the 4 No. 1 straight screw plugs.
Adhesive Toyota Genuine Adhesive 1324, Three Bond 1324 or equivalent Note
Install the 4 No. 1 straight screw plugs within 3 minutes of applying adhesive.
-
Using a 10 mm hexagon socket wrench, install 4 new water hole gaskets and the 4 No. 1 straight screw plugs.
- Torque:
- 44 N*m { 449 kgf*cm, 32 ft.*lbf }
-
-
INSTALL NO. 2 STRAIGHT SCREW PLUG
-
Using a 14 mm hexagon wrench, install 2 new cylinder head screw plug gaskets and the 2 No. 2 straight screw plugs.
- Torque:
- 80 N*m { 816 kgf*cm, 59 ft.*lbf }
-
-
INSTALL NO. 3 STRAIGHT SCREW PLUG
-
Apply adhesive to the 8 No. 3 straight screw plugs.
Adhesive Toyota Genuine Adhesive 1324, Three Bond 1324 or equivalent Note
Install the 8 No. 3 straight screw plugs within 3 minutes of applying adhesive.
-
Using a 10 mm hexagon wrench, install 8 new cylinder head screw plug gaskets and the 8 No. 3 straight screw plugs.
- Torque:
- 65 N*m { 663 kgf*cm, 48 ft.*lbf }
-
-
INSTALL UNION
-
Apply adhesive to the 2 unions.
Adhesive Toyota Genuine Adhesive 1324, Three Bond 1324 or equivalent Note
Install the 2 unions within 3 minutes of applying adhesive.
-
Using a 12 mm union nut wrench, install the 2 unions as shown in the illustration.
*A for Bank 1 *B for Bank 2 *a 55 mm (2.17 in.) *b 30 mm (1.18 in.) - Torque:
- Specified tightening torque
- 14.7 N*m { 150 kgf*cm, 11 ft.*lbf }
Tech Tips
-
*a Torque Wrench Fulcrum Length Calculate the torque wrench reading when changing the fulcrum length of the torque wrench.
-
When using a union nut wrench (fulcrum length of 20 mm (0.787 in.)) + torque wrench (fulcrum length of 300 mm (11.8 in.)): 13.8 N*m (141 kgf*cm, 10 ft.*lbf)
-
-
INSTALL VALVE SPRING SEAT
-
Install the 12 valve spring seats to the cylinder head LH.
-
-
INSTALL INTAKE VALVE STEM OIL SEAL
-
*a Gray *b Black *c Intake Side *d Exhaust Side Apply a light coat of engine oil to 6 new intake 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.
Tech Tips
The intake valve stem oil seals are gray and the exhaust valve stem oil seals are black.
-
*a Correct *b Incorrect Using SST, push in the 6 intake valve stem oil seals to the intake valve guide bushes.
- SST
- 09201-41020
Note
-
Failure to use SST will cause the intake valve stem oil seal to be damaged or improperly seated.
-
Do not push in the intake valve stem oil seal at an angle.
-
-
INSTALL EXHAUST VALVE STEM OIL SEAL
Tech Tips
Use the same procedure as for the intake side.
-
INSTALL EXHAUST VALVE
-
*a 40 mm (1.57 in.) or more Sufficiently apply engine oil to the tip area of the exhaust valve shown in the illustration.
-
Install the 6 exhaust valves, 6 inner compression springs and 6 valve spring retainers to the cylinder head LH.
Note
Install the same parts in the same combination to their original locations.
-
Using SST and wooden blocks, compress the inner compression springs and install the 6 valve spring retainer locks to the valve spring retainers.
- SST
- 09202-70020 ( 09202-01010, 09202-01020 )
