INSPECTION
Perform inspection as follows after removal, installation or replacement of camshaft or valve-related parts, or if
there is unusual engine conditions regarding valve clearance.
In cases of removing/installing or replacing camshaft and valve-
related parts, or of unusual engine conditions due to changes in
valve clearance (found malfunctions during stating, idling or causing
noise), perform inspection as follows:
1.
Remove rocker covers (bank 1 and bank 2). Refer to
2.
Measure the valve clearance as follows:
a.
Set No. 1 cylinder at TDC of its compression stroke.
• Rotate crankshaft pulley clockwise to align timing mark
(grooved line without color) (
) with timing indicator.
• Check that intake and exhaust cam nose on No. 1 cylinder
(engine front side of bank 1) are located as shown in the fig-
ure.
• If not, turn crankshaft one revolution (360 degrees) and align
as shown in the figure.
b.
Use a feeler gauge, measure the clearance between valve lifter
and camshaft.

• By referring to the figure, measure the valve clearances at
locations marked “
×
” as shown in the table below (locations
indicated in the figure).
• No. 1 cylinder at compression TDC
c.
Rotate crankshaft by 240 degrees clockwise (when viewed from engine front) to align No. 3 cylinder at
TDC its compression stroke.
NOTE:
Mark a position 240 degrees (b) from a corner of the hexagonal
part of crankshaft pulley mounting bolt as shown in the figure.
Use the hexagonal part as a guide.
