Bolts-Cylinder Head






NOTE: The cylinder head bolts are tightened using a torque plus angle procedure. The bolts must be examined BEFORE reuse. If the threads are necked down (2) the bolts should be replaced.
Necking can be checked by holding a straight edge against the threads. If all the threads do not contact the scale, the bolt should be replaced.






NOTE: The cylinder head bolts are tightened using an angle torque procedure, however, the bolts are not a torque-to-yield design.

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 thru 12 to 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.)


Bolt-Camshaft

Bearing Cap Bolts 11Nm (100 In.Lbs.)

Non-Oiled Sprocket Bolt 122 Nm (90 Ft.Lbs.)

Intake Manifold

Tighten in sequence shown to 12 Nm (105 in. lbs.).






Exhaust Manifold

Starting at the center arm and working outward, tighten the bolts and nuts to 25 Nm (18 ft. lbs.)
