The mounting pad for the oil pump on the cylinder block can break when objects become trapped between the oil pump drive gears. In many cases, this method of retaining the oil pump housing can be used instead of replacing the cylinder block. This method can be used only if 40 % or more of the oil pump mounting pad can be supported on the broken cylinder block mounting pad.Fabricated Support Block
