Cylinder Liners

Cylinder liners are sleeves that are either cast into the block or installed later. Cast-in cylinder liners are installed in the mold, and the aluminum is poured around them. They become a permanent part of the block. Two kinds of liners, dry and wet, can be installed later. Dry liners are pressed in. They touch the cylinder bore along their full length. Wet liners touch the cylinder block only at the top and bottom. The rest of the liner touches only the coolant. Pressed-in dry liners and wet liners are replaced if they become worn or damaged
