3-50. CYLINDER LINERS AND CYLINDER BLOCK MAINTENANCE (Contd)
NOTE
Most attempts to hone or deglaze cylinder liners provide worse
results than leaving them "as is." Experience and laboratory
results indicate that liners do not need to be honed or deglazed
to provide proper ring setting.
It is recommended that cylinder liners be inspected before
cleaning so defects can be clearly noted.
Inspect cylinder liners closely for any of the metal conditions
illustrated. If one liner has failed. then other liners in the same
engine are likely to have early signs of the same type failure.

if cracked.
