Cylinder Head
After torquing, tighten all cylinder head bolts in two steps (90°per step). If you are using a new cylinder head bolt, tighten the bolt an extra 90°
Head Bolt
Measure the diameter of each cylinder head bolt at point A and point B.
If either diameter is less than 10.6 mm (0.42 in.), replace the cylinder head bolt.
Surface Variation
Warpage less than 0.05 mm (0.002 in.) no resurfacing
Warpage between 0.05 mm (0.002 in.) & 0.2 mm (0.008 in.) resurface
Max. resurface limit 0.2 mm (0.008 in.)
based on a height of 104 mm (4.09 in.).
Intake Manifold
Camshaft Bearing/Holder
Camshaft Gear/Sprocket
Exhaust Manifold
Tighten the bolts/nuts in a crisscross pattern in three steps, beginning with the inner nut.

- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
