Abstract: In a cylinder block of an internal combustion engine, crank caps are bolted and a crankshaft is rotatably supported by the crank caps. The cylinder block includes bulkheads which divide an internal space of a crankcase into sub-sections for respective cylinders of the engine. Breathing holes are formed in each of the bulkheads and allow the sub-sections of the crankcase to communicate with each other via the breathing holes. Crank cap holes are formed in a bottom of each of the bulkheads. Bolts are fastened to the crank cap holes to fix the crank caps to the bulkheads. The crank cap holes are threaded holes which extend from the bottom of each of the bulkheads and are open to the breathing holes.

Abstract: A restoration sleeve for the remanufacture of cast iron engine blocks or aluminum blocks with cast iron liners includes a sleeve formed of cast iron and having a relatively thin wall, a selected length, an outer diameter to achieve a non-interference fit within an overbored cylinder, an inner diameter equal to the original specifications of the original manufacturer of the engine block, and a helical cross hatched inner surface finish. The sleeves are manufactured by placing an unfinished sleeve in a boring fixture, boring the inner surface to a selected diameter, transferring the bored sleeve to a honing fixture, and honing the inner surface to the required diameter and surface finish. An adhesive is applied to the restoration sleeve and the overbored block cylinders, and the sleeves are inserted into the overbored cylinders wherein the adhesive is allowed to cure to thereby adhesively retain the sleeves within the block. A fluorescent dye is used in the adhesive for inspection by ultraviolet light to insure continuous and complete application of the adhesive to the restoration sleeve and the bored cylinder surface.

Abstract: Method of dimensionally stabilizing the interface between metal parts of differing thermal expansion characteristics (TEC), regardless of temperature variations under normal designed use of such parts, comprising: (a) hot extruding a mixture of ceramic fibers (i.e., Si.sub.3 N.sub.4, SiC, Al.sub.2 O.sub.3) and a powder of the metal having the higher TEC (i.e., Al, Ti, Mg) while aligning the fibers generally along the direction of extrusion, to form an insert; (b) shaping the insert to align its fibers generally in at least one direction of anticipated thermal growth that may interfere with the interface; (c) casting the insert in place within a first part compound of the higher TEC metal and with the insert's fibers (i) oriented as above, and (ii) preheated to a temperature no greater than 35-45% of the temperature of the molten light metal; and (d) bringing together the first metal part with a second part of lower TEC metal (i.e., Fe or steel) to form the interface. The insert may be located in a mold in a manner to be totally enveloped by the molten light metal with the insert having a surface spaced a uniform, predetermined distance from the exterior of the cast light metal part, or the insert may be located to expose a surface thereof upon completion of the casting.
