PROCEDURE

1. INSTALL INTAKE VALVE GUIDE BUSH

(1) Using a caliper gauge, measure the intake valve guide bush bore diameter of the cylinder head sub-assembly.

Standard Intake Valve Guide Bush Bore Diameter:

10.285 to 10.306 mm (0.405 to 0.406 in.)

Standard Bush Length:

41.3 to 41.7 mm (1.63 to 1.64 in.)

HINT:

• If the intake valve guide bush bore diameter of the cylinder head sub-assembly is more than 10.306 mm (0.406 in.), machine the intake valve guide bush bore of the cylinder head sub-assembly to a dimension of 10.335 to 10.356 mm (0.407 to 0.408 in.) to install an O/S 0.05 intake valve guide bush.
• If the intake valve guide bush bore diameter of the cylinder head sub-assembly is more than 10.356 mm (0.408 in.), replace the cylinder head sub-assembly.

(2) Heat the cylinder head sub-assembly to between 80 and 100°C (176 and 212°F).

CAUTION:

Be sure to wear protective gloves.

(3) Using SST and a hammer, tap in the selected intake valve guide bush.

SST: 09201-10000

09201-01050

SST: 09950-70010

09951-07100

Standard Protrusion Height:

13.35 to 13.60 mm (0.526 to 0.535 in.)

(4) Using a sharp 5.5 mm reamer, ream the intake valve guide bush to obtain the standard oil clearance.

Standard Oil Clearance:

0.025 to 0.060 mm (0.000984 to 0.00236 in.)

2. INSTALL EXHAUST VALVE GUIDE BUSH

(1) Using a caliper gauge, measure the intake valve guide bush bore diameter of the cylinder head sub-assembly.

Standard Intake Valve Guide Bush Bore Diameter:

10.285 to 10.306 mm (0.405 to 0.406 in.)

Standard Bush Length:

43.3 to 43.7 mm (1.70 to 1.72 in.)

HINT:

• If the intake valve guide bush bore diameter of the cylinder head sub-assembly is more than 10.306 mm (0.406 in.), machine the intake valve guide bush bore of the cylinder head sub-assembly to a dimension of 10.335 to 10.356 mm (0.407 to 0.408 in.) to install an O/S 0.05 intake valve guide bush.
• If the intake valve guide bush bore diameter of the cylinder head sub-assembly is more than 10.356 mm (0.408 in.), replace the cylinder head sub-assembly.

(2) Heat the cylinder head sub-assembly to between 80 and 100°C (176 and 212°F).

CAUTION:

Be sure to wear protective gloves.

(3) Using SST and a hammer, tap in the selected intake valve guide bush.

SST: 09201-10000

09201-01050

SST: 09950-70010

09951-07100

Standard Protrusion Height:

13.75 to 14.00 mm (0.541 to 0.551 in.)

(4) Using a sharp 5.5 mm reamer, ream the intake valve guide bush to obtain the standard oil clearance.

Standard Oil Clearance:

0.030 to 0.065 mm (0.00118 to 0.00256 in.)

3. INSTALL SPARK PLUG TUBE

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

(1) Apply adhesive to 4 new spark plug tubes as shown in the illustration.

Adhesive:

Toyota Genuine Adhesive 1324, Three Bond 1324 or equivalent

NOTICE:

• Install the spark plug tubes within 3 minutes of applying adhesive.
• Be careful not to deform the spark plug tubes.
• Do not expose the spark plug tubes to engine oil for at least 1 hour after installing them.

(2) Using a wooden block and hammer, tap in the 4 spark plug tubes to the specified protrusion height.

Standard Protrusion Height:

77.3 to 78.3 mm (3.04 to 3.08 in.)

NOTICE:

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

4. INSTALL RING PIN

(1) Using a plastic hammer, tap in 2 new ring pins to the specified protrusion height.

Standard Protrusion Height:

6.5 to 7.5 mm (0.256 to 0.295 in.)

5. INSTALL STUD BOLT

NOTICE: If a stud bolt is deformed or its threads are damaged, replace it.

(1) Using an E8 "TORX" socket wrench, install the 7 stud bolts.

Torque:

6.5 N·m {66 kgf·cm, 58 in·lbf}

6. INSTALL NO. 1 STRAIGHT SCREW PLUG

(1) Apply adhesive to the 4 No. 1 straight screw plugs.

Adhesive:

Toyota Genuine Adhesive 1324, Three Bond 1324 or equivalent

NOTICE:

Install the No. 1 straight screw plugs within 3 minutes of applying adhesive.

(2) Using a 6 mm hexagon wrench, install the 4 No. 1 straight screw plugs to the cylinder head sub-assembly.

Torque:

25 N·m {255 kgf·cm, 18 ft·lbf}

7. INSTALL INTAKE VALVE SPRING SEAT

8. INSTALL EXHAUST VALVE SPRING SEAT

9. INSTALL INTAKE VALVE STEM OIL SEAL

(1) Apply a light coat of engine oil to 8 new valve stem oil seals.

NOTICE:

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.

HINT:

The intake valve stem oil seals are gold and the exhaust valve stem oil seals are gray.

(2) Using SST, push in the 8 valve stem oil seals.

SST: 09201-41020

NOTICE:

• Failure to use SST will cause the valve stem oil seals to be damaged or improperly seated.
• Do not push in the valve stem oil seals at an angle.

10. INSTALL EXHAUST VALVE STEM OIL SEAL

(a) Perform the same procedure as for the intake side.

11. INSTALL INTAKE VALVE

(1) Sufficiently apply engine oil to the tip area of the intake valve shown in the illustration.

(2) Install the 8 intake valves to the cylinder head sub-assembly.

12. INSTALL EXHAUST VALVE

(a) Perform the same procedure as for the intake side.

13. INSTALL INTAKE VALVE COMPRESSION SPRING

NOTICE: Install the inner compression spring with its tapered side facing upward (towards the valve spring retainer). Install the same parts in the same combination to their original locations.

14. INSTALL EXHAUST VALVE COMPRESSION SPRING

NOTICE: Install the inner compression spring with its tapered side facing upward (towards the valve spring retainer). Install the same parts in the same combination to their original locations.

15. INSTALL VALVE SPRING RETAINER

16. INSTALL VALVE SPRING RETAINER LOCK

(1) Using SST, compress the inner compression spring and install the 8 valve spring retainer locks.

SST: 09202-70020

09202-01010

09202-01020

SST: 09202-00021

(2) Using a plastic hammer, lightly tap the valve stem tip to ensure a proper fit.

NOTICE:

• Be careful not to damage the valve stem tip.
• Be careful not to damage the valve spring retainer.
