Using a vernier caliper, measure the diameter of the elongated thread at the measuring point.

• Measuring point:
• 94 mm (3.70 in.) for intake side bolt
• 89 mm (3.50 in.) for exhaust side bolt

• Standard diameter:
• 10.85 to 11.00 mm (0.427 to 0.433 in.)

• Minimum diameter:
• 10.6 mm (0.417 in.)

If the diameter is less than the minimum, replace the cylinder head bolt.

• HINT:

• If a visual check reveals no excessively thin areas, check the center of the bolt (see illustration) and find the area that has the smallest diameter.

Using a precision straightedge and feeler gauge, measure the warpage of the surfaces where the cylinder head contacts the cylinder block and manifold.

• Standard Warpage:

• Item	Specified Condition
  Cylinder head lower side	0.05 mm (0.00197 in.)
  Intake side	0.08 mm (0.00315 in.)
  Exhaust side	0.05 mm (0.00197 in.)

• Maximum warpage:
• 0.10 mm (0.00394 in.)

If the warpage is more than the maximum, replace the cylinder head.

Using a dye penetrant, check the intake ports, exhaust ports and cylinder surface for cracks.

If cracked, replace the cylinder head.

Clean the cylinder block with solvent.

Set the piston of the No. 1 cylinder to slightly ATDC.

Place the cylinder head gasket on the cylinder block surface with the front face of the Lot No. stamp upward.

• NOTICE:

Place the cylinder head on the cylinder block.

• NOTICE:

• HINT:

• The cylinder head bolts are tightened in 3 progressive steps.

Apply a light coat of engine oil to the threads and under the heads of the cylinder head bolts.

Step 1:

Step 2:

Step 3:

Install and uniformly tighten the 2 bolts in the sequence shown in the illustration.

• Torque:
• 21 N*m{ 214 kgf*cm, 15 ft.*lbf}

Apply a light coat of engine oil to the valve stem caps.

Install the 32 valve stem caps to the cylinder heads.

Inspect the valve lash adjuster before installing it ().

Install the 32 valve lash adjusters to the cylinder heads.

• NOTICE:

• Install the lash adjuster to the same place it was removed from.

Apply engine oil to the lash adjuster tips and valve stem cap ends.

Install the 32 valve rocker arms as shown in the illustration.
