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.

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.

*a

*c

Protrusion Height

-

-

(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.
