plate washer will pass through the cylinder head and cylinder
block into the oil pan.

NOTE:



As the thrust clearance of the camshaft is small, the camshaft must
be kept level while it is being removed. If the camshaft is not kept
level, the portion of the cylinder head which receives the shaft thrust
may crack or be damaged. To avoid this, the following steps should
be carried out.
