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.
1.
Remove rocker cover. Refer to
2.
Measure the valve clearance with the following procedure:
a.
Set No. 1 cylinder at TDC of its compression stroke.
• Rotate crankshaft pulley
clockwise and align TDC mark (no
paint)
to timing indicator
on front cover.
• At the same time, check that both intake and exhaust cam
noses of No. 1 cylinder face inside (
) as shown in the figure.
• If they do not face inside, rotate crankshaft pulley once more
(360 degrees) and align as shown in the figure.
b.
Using a feeler gauge, measure the clearance between valve
lifter and camshaft.

cated with black arrow (
) in the figure] with a feeler gauge.
3.
If out of standard, perform adjustment. Refer to “ADJUSTMENT”.
