    Abstract: A method for remanufacturing an engine block is provided. The engine block includes a damaged area on an inner surface of a cylinder. The method includes removing a first liner from the cylinder. The first liner includes a first inner diameter defined by a first inner surface and a first outer diameter defined by a first outer surface. The method includes removing material from the damaged area on the inner surface of the cylinder. The method also includes providing a machined surface on the inner surface of the cylinder. The machined surface defining a machined diameter. The method further includes inserting a second liner into the cylinder. The second liner includes a second inner diameter defined by a second inner surface and a second outer diameter defined by a second outer surface. The second outer diameter is equal to the machined diameter.
