In a diesel engine, a cylinder liner should be replaced if it is __________. scuffed Scored

🔍 Key Concepts

• Cylinder liner wear and damage types in diesel engines (normal wear vs. damage that requires immediate replacement) • Difference between scuffing and scoring on a liner surface • Manufacturer limits and inspection criteria for re-use vs. replacement of liners

💭 Think About

• Think about what happens to cylinder pressure, lubrication, and piston ring life if a liner is scuffed or scored. Does either condition seriously affect sealing and lubrication? • Consider whether scuffing and scoring are usually treated as minor, repairable conditions or as serious damage that typically requires replacement. • Ask yourself if one of these terms might describe surface damage that can sometimes be polished/honed out, while the other indicates deeper damage.

✅ Before You Answer

• Verify which condition(s) lead to loss of proper oil film and risk of seizure between piston and liner. • Check whether either scuffed or scored liners may be safely reused after honing, according to typical marine diesel maintenance practice. • Confirm from your study materials which types of liner damage are listed under "renew liner" or "replace liner" rather than "dress" or "hone".
