Cylinder Head Assembly
CYLINDER HEAD
Tighten the bolts in sequence using the following steps and torque values:
Step 1: Tighten bolts 1-8 27 Nm (20 ft. lbs.).
Step 2: Verify that bolts 1-8, all reached 27 Nm (20 ft. lbs.), by repeating step-1 without loosening the bolts.
Tighten bolts 9 through 12 14 Nm (10 ft. lbs.).
Step 3: Tighten bolts 1-8 90 degrees.
Step 4: Tighten bolts 1-8 90 degrees, again.
Tighten bolts 9-12 26 Nm (19 ft. lbs.)
HEAD BOLT RE-USABILITY
The bolts must be examined BEFORE reuse. If the threads are necked down the bolts should be replaced.
SURFACE VARIATION
If measurements exceed 0.0508 mm (0.002 in.) replace the cylinder head.
CAMSHAFT BEARING CAP
Tighten the camshaft bearing cap retaining bolts 11 Nm (100 in. lbs.).
