When carrying out major repairs yourself, various options are possible. The decision to replace the cylinder block, connecting rod-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 auto repair shop equipment, availability of parts, the time it takes to complete 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-piston group and crankshaft should be carefully examined. Even if minor wear of the cylinder block is detected, the cylinders are subject to mandatory honing.
Complete crankshaft
This rebuild kit includes a reground crankshaft and a set of matched pistons and connecting rods. The pistons are already installed on the connecting rods. The kit also includes a set of piston rings, main and connecting rod bearings. These kits typically contain pistons in both standard and all oversize sizes.

Incomplete cylinder block
An incomplete cylinder block contains a cylinder block with an installed crank mechanism and piston group. The kit includes new main and connecting rod bearings, and all clearances comply with standards. The kit includes the existing camshaft, valve mechanism, cylinder head and attachments. Mechanical processing costs are minimal or not required at all.
Complete cylinder block
The complete cylinder block contains the entire assembly of the incomplete cylinder block, as well as the oil pump, oil pan, cylinder head, camshaft bearing housing cover, camshaft, valve train, camshaft drive gears, timing belt and belt covers. All parts are installed with new bearings, seals and gaskets. Only intake and exhaust manifolds and attachments are installed on the kit.
Carefully consider which alternative is best for you, and consult with your local auto repair shop, parts suppliers, and parts retailers before purchasing parts.
