The decision on replacement of the block of cylinders, shatunno-piston group and a cranked shaft depends on a number of factors from which the most important is the condition of the block of cylinders. Other reasons are repair cost, possibility of access to the equipment of workshops of car-care center, existence of spare parts, time planned for work, and also personal experience.
Here alternatives some of options to major maintenance.
Acquisition of separate spare parts
If check shows that the block of cylinders and the majority of details are in a satisfactory condition and can be used further, the most expedient from the economic point of view is purchase of separate spare parts.

Block of cylinders
incomplete complete set

All interfaced details are picked up for the dimensional groups, all gaps correspond to norms. On the block camshafts, the klapanny mechanism, a head of the block of cylinders and hinged units are separately mounted. Costs of machining are minimum or are not required absolutely.
The restored engine
The restored engine contains all set of the block of cylinders of an incomplete complete set, and also the oil pump, the oil pallet, a head of the block of cylinders, a cover of a head of the block of cylinders, camshafts, the klapanny mechanism, pulleys / asterisk of a drive of camshafts, gear a belt / chain and covers.
