  Q: What additional engine repair information is available for piston ring service and repair, and what does Unit Repair encompass for engine overhaul on Cadillac Catera?

  A: The service documentation for Piston rings exists separately but in case an internal engine part does not contain unique service procedures it implies the manufacturer left it without special guidance. Unit repair encompasses essential service procedures, machining, cleaning, inspection, and fitting necessary for engine overhaul, including cylinder boring and honing, fitting of connecting rod and bearings, fitting of Crankshaft and bearings, replacement of camshaft bearings, disassembly of connecting rod and Piston, disassembly of the Cylinder Head, servicing of valve train components (valves, seats, springs, rockers, etc.), disassembly of the Oil Pump, fitting of pistons and rings, thread repair information, valve and seat grinding (valve job), and servicing of timing components (chain, belt, gears).
