16. Remove collared O-ring from front timing chain case (left and right side).
17. Remove rocker covers (right and left banks). Refer to EM-51, "
ROCKER COVER" .
NOTE:
When only timing chain (primary) is removed, rocker cover does not need to be removed.
18. 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 (grooved line without color) with timing indicator.
b. Make sure that intake and exhaust cam noses on No. 1 cylinder (engine front side of right bank) are located as shown in the fig-
ure.

If not, turn crankshaft one revolution (360 degrees) and align
as shown in the figure.
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 EM-72,
"INSTALLATION" .
19. Remove crankshaft pulley as follows:
