Checking Valve Clearance
NOTE: The engine does not need to be removed

from the vehicle for this procedure.
1. Disconnect the negative battery cable; then remove
the valve cover (see REMOVE AND INSTALL
VALVE COVER).
NOTE: There are two intake and two exhaust

valves per cylinder. The intake camshaft and valves
are next to the intake manifold and the exhaust cam-
shaft and valves are next to the exhaust manifold.
2. Remove the spark plugs, making sure no dirt or for-
eign material enters the cylinders.
