ABSTRACT:
A method for repairing the cylinder block of an internal combustion engine. The cylinder block engages a standard cylinder head and includes an outer cylinder casting that surrounds an inner cylinder sleeve. The casting has corrosion formed in an end surface that faces the cylinder head. The method includes the steps of providing a repair ring that is separate and distinct from the cylinder sleeve and has a selected thickness. A counterbore is formed in the end surface of the cylinder casting to remove the corrosion therefrom. The counterbore has a depth that is no greater than the thickness of the ring. The ring is installed annularly about and in close tolerance fit with the cylinder sleeve and is introduced into the counterbore. At least one of the cylinder sleeve and the ring are machined for form thereon respective, generally co-planar surfaces that face the cylinder head.
