INSPECTION AFTER INSTALLATION
After installing the fuel tubes, make sure there are no fuel leaks at the connections using the following steps.
1.
Apply fuel pressure to the fuel lines by turning ignition switch ON (with engine stopped). Then check for
fuel leaks at the connections.
2.
Start the engine and rev it up and check for fuel leaks at the connections.
WARNING:
Do not touch engine immediately after stopping, as engine becomes extremely hot.
NOTE:
Use mirrors for checking on hidden points.

13. Remove collared O-rings from front timing chain case (left and
right side).
14. Remove rocker covers (right and left banks). Refer to
EM-41, "Removal and Installation"
.
NOTE:
When only timing chain (primary) is removed, rocker cover does not need to be removed.
15. Obtain No. 1 cylinder at TDC of its compression stroke as follows:
NOTE:
When timing chain is not removed/installed, this step is not required.
a.
Rotate crankshaft pulley clockwise to align timing mark (A)
(grooved line without color) with timing indicator (B).
b.
Make sure that intake and exhaust cam noses on No. 1 cylinder
(engine front side of right bank) are located as shown.
• If not, turn crankshaft one revolution (360
°
) and align as
shown.
NOTE:
When only timing chain (primary) is removed, rocker cover does
not need to be removed. To make sure that No. 1 cylinder is at
its compression TDC, remove front timing chain case first. Then
check mating marks on camshaft sprockets. Refer to
16. Remove crankshaft pulley as follows:
a.
