<p>A cylinder liner for an internal combustion engine provides a method of replacement of spent cylinder liners, wherein the cylinder liner comprises a generally cylindrical body having a flange extending radially outwardly defining a shoulder. The shoulder provides a positive stop in an axial direction against a surface within a cylinder block of the engine. The body has an engagement portion adjacent the shoulder. The engagement portion is necked down from the flange and has lower and upper portions providing an interference fit within the cylinder block that inhibits fluid flow between the lower and upper portions and the cylinder block. The lower and upper portions of the engagement portion are separated from one another by a channel that extends substantially about the circumference of the body.</p>
