10. Adjust valve clearance setting with each piston in
turn at Top Dead Centre, and rockers free to move,
Fig. 10.
Intake Valve clearance,
0.36-0.46 mm (0.014-0.018 in).
Exhaust Valve clearance,
0.43-0.53 mm (0.017-0.021 in).
NOTE: Valve clearance is to be set, only when the engine

11. Install the injectors with new seat washers, cork
seals, and torque to 23 N m (17 lbf.ft) Fig. 11.
Install the injector lines and torque to 24 Nm (18
lbf.ft). Install the leak off line with new washers, and
torque the leak off banjo bolts to, 6 Nm (4.4 lbf.ft).
NOTE: Hold the leak off plastic tubing when tightening to
prevent the pipes pivoting, during torque up.
12. Exhaust manifold bolts are to be refitted and tight-
ened to a torque of, 38 Nm (28 lbf.ft).
Intake manifold bolts are to be refitted and tightened
to a torque of, 38 Nm (28 lbf.ft).
13. Using new gaskets install intake and exhaust mani-
folds. Initially install all bolts finger tight ensuring the
gaskets are aligned with the inlet and exhaust ports.
Tighten the bolts to a torque of 61 Nm working from
the central bolts outwards.
Re tighten the bolts to a torque of 61 Nm.
NOTE: When the manifold bolts are torqued the gaskets
may show signs of distortion between the inlet and exhaust
ports. This is normal for this type of gasket and is the rea-
son for the retorquing procedure.
