Checking Guide For Valve Tappets

Before installing the valve tappet guide in the cylinder head, check it for damage or existing defects. The valve tappet guide must be replaced if it displays irregularities deviating from the limit sample photo.

The irregularities shown in the limit sample photo are normal and must not be classified as damage influencing the function of the part or requiring replacement of the part.
