NOTICE:
Correct torque on the high-pressure fuel lines is critical.
Incorrect torques could result in leaks or lack of power due
to restricted fuel flow.
9. Without moving the transfer-tube thrust bolt, install the high-pressure fuel line as removed.
[a]
When installing the transfer-tube fitting, use one wrench to hold the thrust bolt, and
another to tighten the fitting.
[b]
Tighten the fitting to 30 N·m (22 lb·ft).
[c]
Remove the wrench used to hold the location of the thrust bolt.
10. Install new exhaust manifold gaskets on all exhaust ports. Make sure the gaskets are all
positioned correctly.
NOTE:
Install new manifold gaskets on all exhaust ports, regardless of how many heads were removed.
11. Install the exhaust manifold and tighten the bolts to 50 N·m (37 lb·ft).
12. Install the charge-air intake manifold.
13. Lubricate the pushrods with a light coating of engine oil and install the pushrods, in order, as
removed.
NOTE:
Make sure the pushrods are correctly seated in the valve tappets.
14. Install the valve bridges, in order, as removed.
15. Install the rocker arm assembly, in order, as removed. Tighten each rocker arm mounting bolt
first to 60 N·m (44 lb·ft); then an additional 90 degrees. Refer to section 1.22.4.
16. Install the barring tool and adjust the valves. For valve lash adjustment procedures, refer to
section 1.20.3.
17. Remove the barring tool. Refer to section 1.16.1.
18. Install the inspection hole end cover on the flywheel housing. Tighten the fasteners 25 N·m
(18 lb·ft).
19. Check that the coolant drain plug is tight and not leaking.
