What is the function of cylinder liner?

Why does a diesel engine have a cylinder liner?
Liners are cylindrical surface elements capable of retaining a thin oil film on the inner surface. When inserted into the cylinder of the engine block, they protect the engine from wear and piston sliding action.

When should I replace my cylinder liner?
Check the cylinder liner for cracks, loose parts or scratches. If any cracks, wear or scratches are found, the cylinder must be replaced with a new one. If this is not the case, continue to look for cavitation on the liner.

When should the cylinder be sleeved?
The general rule is to reinstall the sleeve when there is no piston available larger than the current cylinder size. If you leave the toy in place long enough, this usually allows you to drill the cylinder multiple times before you have to re-sleeve it again.
