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 criteria for determining the need for major repairs include the cost of repairs, access to auto service workshop equipment, 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 economical 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
Contains a cylinder block with an installed crank mechanism and piston group. The kit includes new main and connecting rod bearing shells, all clearances comply with standards. The kit includes the existing camshaft, valve mechanism, cylinder head and ancillary units. 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 timing belt pulley, timing belt and belt covers. All parts are installed with new bearings, seals and gaskets. The kit only includes intake and exhaust manifolds and attachments. Consider carefully which alternative is best for you; before purchasing parts, consult with a car service center, suppliers, and spare parts sellers.
