INSPECTION
NOTE:
Perform the following inspection after removal, installation or replacement of camshaft or valve-related parts,
or if there are unusual engine conditions due to changes in valve clearance over time (starting, idling, and/or
noise).
1. Warm up the engine. Then stop the engine.
2. Remove the air cleaner and resonator assembly. Refer to
EM-25, "Removal and Installation"
3. Remove the RH bank and LH bank rocker covers using power tool. Refer to
.
4. Turn the crankshaft pulley in the normal direction (clockwise
when viewed from engine front) to align TDC identification notch
(without paint mark) with timing indicator.
5. At this time, make sure both the intake and exhaust cam noses
of No. 1 cylinder (top front on LH bank) face outside.
• If they do not face outside, turn crankshaft pulley once more.

6. Measure valve clearances at the locations marked “
×” as shown
in the table below (locations indicated with black arrow).
•
: Engine front
•
(black): Measurable at No.1 cylinder compression top dead
center
•
(white): Measurable at No. 3 cylinder compression top
dead center
• A: RH
• B: LH
• C: Exhaust
• D: Intake
NOTE:
Firing order 1-8-7-3-6-5-4-2
• No. 1 cylinder compression TDC
• Measure valve clearance using suitable tool. Refer to
CAUTION:
If the inspection was carried out with a cold engine, make
sure the values with a fully warmed up engine are still
within specifications.
7. Turn the crankshaft pulley clockwise 270
° from the position of No. 1 cylinder compression TDC to obtain
No. 3 cylinder compression TDC.
