When performing a major overhaul on your own, there are various options. The decision to replace the cylinder block, connecting rod and piston group, and crankshaft depends on a number of factors, the most important of which is the condition of the cylinder block. Other considerations include the cost of repairs, access to the equipment of the car service workshop, availability of spare parts, the time planned for the work, and personal experience.
Here are some of the options for carrying out major repairs.
Purchase of individual spare parts
If the inspection shows that the cylinder block and most of the parts are in satisfactory condition and can be used in the future, then the most economically feasible option is to purchase individual spare parts. The cylinder block, connecting rod and piston group and crankshaft should be examined especially carefully. Even if minor wear of the cylinder block is detected, the cylinders are subject to mandatory honing.
Incomplete cylinder block
The incomplete cylinder block contains a cylinder block with a crank mechanism and piston group installed. All mating parts are selected according to size groups, all clearances comply with the standards. The camshaft, valve mechanism, cylinder head and attachments, which are not included in this repair kit, are mounted separately on the block. The costs of mechanical processing are minimal or not required at all.
Engine repair (complete cylinder block)
The overhaul engine supplied as spare parts contains the entire set of the incomplete cylinder block, as well as the oil pump, oil pan, cylinder head, cylinder head cover, camshaft, valve mechanism, camshaft drive gears, toothed belt and belt covers. All parts are installed with new bearings, seals and gaskets. Only the intake and exhaust manifolds and attachments are mounted on the set.
Consider carefully which of the alternatives is best for you. Before purchasing or placing an order for spare parts, consult your local car service workshop, spare parts suppliers, and engine repair specialists.
