Here are the few facts with which the do-it-yourselfer needs to be confronted when considering a rebuilt engine, the price, warranty, availability of parts, and time for completion. The decision to change parts such as the engine block, piston/connecting rod assemblies, as well as crankshaft hinges on the last inspection of the engine and tell whether it should overhaul the in-stock engine or should buy an exchange engine. It is possible to buy individual bits if the components of the engine are separable, or, if not, get a short block that already has the crankshaft and piston/connecting rod assemblies put in, or, if not, a long block that comes with extra accessories such as an oil pump and the cylinder head. There are also low mileage used engines which are imported from crushed cars or from areas of high turnover, which also come with a warranty the same as new remanufactured engines. Any choice should be taken very seriously and it is recommended to talk with automotive machine shops, auto parts' dealers, and rebuilders.

Label and disconnect all vacuum lines, hoses, electrical connectors, and ground straps, using masking tape for marking.

It is important to anticipate that the vehicle may be out of use for an extended period, and consulting a machine shop for an estimate on the time required for any necessary rebuilding or repairs is recommended.

Before beginning engine reassembly, ensure you have all the necessary new parts, gaskets, and seals, along with common hand tools, a 1/2-inch drive torque wrench, new engine oil, gasket sealant, and thread locking compound.

Rebuilding alternatives include purchasing individual parts if the components are reusable, opting for a short block with a crankshaft and piston/connecting rod assemblies already installed, or selecting a long block that includes additional components like an oil pump and cylinder head.

If obtaining a short block, the timing chain or belt, cylinder head(s), oil pan, oil pump pick-up tube, oil pump, and water pump should be removed to turn in the old short block to the rebuilder as a core.

It is much easier to remove the external components if the engine is mounted on a portable engine stand, which can often be rented cheaply from an equipment rental yard.

Support the engine/transaxle assembly with a hoist, ensuring proper balance, and disconnect any remaining connections before removing the mounts and carefully lifting the assembly out of the vehicle.

A suitable workspace is crucial as it requires adequate space for the vehicle and storage. If a shop or garage isn't available, a flat, level, clean surface made of concrete or asphalt is essential.
