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. Warm up engine. Then stop it.
2. Open splash guard on RH undercover.
3. Remove rocker cover. Refer to EM-42, "
ROCKER COVER" .

tions marked “X” as shown in the table below (locations indi-
cated with black arrow in figure) with a feeler gauge.
