Determine maximum allowable refacing dimension using distance measured and minimum dimension.
Distance measured minus minimum dimension = maximum permissible refacing dimension.
Note: If the maximum allowed refaced dimension is 0 mm or less than 0 mm, repeat measurement using new valve. If measurement result is still 0
mm or less than 0 mm, replace cylinder head.
