System Specifications

Cylinder Head
CYLINDER HEAD LH
Install the 8 cylinder head bolts.

HINT:
The cylinder head bolts are tightened in 2 successive steps (Procedures "A" and "B").
If any cylinder head bolt is broken or deformed, replace it.

Using several steps, tighten each bolt uniformly with a 10 mm bi-hexagon wrench in the sequence as shown in the illustration (Procedure "A").
Torque 36 Nm (367 kgf/cm, 27 ft. lbs.)
If any one of the cylinder head bolts does not meet the torque specification, replace the cylinder head bolt.

Mark the front side of each cylinder head bolt with paint.
Retighten the cylinder head bolts 180° as shown (Procedure "B").
Check that the painted marks are now at 180° opposite to the engine front.

Install the 2 cylinder head bolts.
Using several steps, install and tighten the 2 cylinder head bolts uniformly in the sequence as shown in the illustration.
Torque 30 Nm (306 kgf/cm, 22 ft. lbs.)

CYLINDER HEAD SUB-ASSEMBLY
Install the 8 cylinder head bolts.

HINT:
The cylinder head bolts are tightened in 2 successive steps (Procedures "A" and "B").
If any cylinder head bolt is broken or deformed, replace it.

CYLINDER HEAD SET BOLT
Using vernier calipers, measure the outside thread diameter of the bolt.
Standard outside diameter 10.85 to 11.00 mm (0.4272 to 0.4331 in.)
Minimum outside diameter 10.7 mm (0.421 in.)

Inspect warpage.
Using a precision straight edge and feeler gauge, measure the warpage of the contact surfaces of the cylinder block and manifolds.
Maximum warpage 0.10 mm (0.0039 in.)
If warpage is greater than the maximum, replace the cylinder head.

Inspect cranks.
Using a dye penetrant, check the combustion chamber, intake ports, exhaust ports and cylinder block surface for cracks.
If cracked, replace the cylinder head.
