The do-it-yourselfer faces several choices when performing an engine overhaul, with the primary consideration being the condition of the engine block, alongside factors such as cost, access to machine shop facilities, parts availability, time required for completion, and prior mechanical experience. Rebuilding alternatives include purchasing individual parts if the engine block and components are reusable, which can be the most economical option, though careful inspection is necessary, especially for the cylinder bores. A short block, which includes an engine block with an installed crankshaft and piston/connecting rod assemblies, offers a convenient solution with new bearings and correct clearances, allowing for easy attachment of existing components. A long block expands on this by including additional parts such as an oil pump, oil pan, cylinder heads, and all necessary seals and gaskets, requiring only the installation of manifolds and external parts. It is advisable to consider which alternative suits your needs best and to consult with local automotive machine shops, auto parts dealers, and experienced rebuilders before making any purchases.

Careful assembly in a clean environment is vital for ensuring the longevity and reliability of the rebuilt engine.

When acquiring a short block, the cylinder head(s), oil pan, and oil pump will also need to be removed.

Remove the engine and transaxle mounts, then carefully lift the assembly out of the vehicle, turning as needed to avoid obstructions. Once clear, lower the assembly onto a work surface.

Several preliminary steps should be taken, including locating a suitable place to work, cleaning the engine compartment, ensuring the right equipment is available, and planning the operation ahead of time.

For a four-cylinder engine, the general order for reassembly is: 1. Piston rings 2. Crankshaft and main bearings 3. Piston/connecting rod assemblies 4. Rear main oil seal 5. Cylinder head 6. Camshafts and rockers 7. Valve cover 8. Oil pump 9. Oil pick-up 10. Oil pan 11. Timing belt and sprockets 12. Timing belt cover 13. Intake and exhaust manifolds 14. Flywheel/driveplate.

Mount each bolt in a vise and run a die down the threads to remove corrosion.

The first step is to thoroughly clean the cylinder head(s) and related valve train components, followed by a detailed inspection to determine how much valve service work must be done during the engine overhaul.

Apply a small dab of grease to each keeper if necessary to hold it in place.

Due to the necessity of specialized tools for disassembly and inspection, along with the potential unavailability of replacement parts, it may be more economical to buy replacement heads rather than disassembling, inspecting, and reconditioning the originals.
