How to Rebuild a Cheap Car Engine
Car engines come in a variety of designs. Elements such as the cylinder block and ignition system are common to all car engines. These elements are classified based on the number of cylinders, the geometry of the block or the type of ignition used in an engine. When engines begin malfunctioning, the first instinct is to get rid of the car. Rebuilding the engine, however, can save you this huge expenditure.

Drain the oil from the engine. When rebuilding your engine, dirt can be your worst enemy. Once clean, move it to a space that can be used for car repairs and use a service manual to disassemble the engine.

Inspect the engine parts. When dissembling the engine, examine each part carefully for signs of wear. Look for discoloration or any aluminum that may have melted and stuck to components. Isolate the problem in the motor to mitigate the possibility of another breakdown. If the problem is not fixed, the engine is likely to fail again.

Check the cylinder head for cracks or any other problems. This can occur if the engine is overheated. When the engine overheats, aluminum overhead "cam heads" are more likely to warp and develop cracks than the cast-iron heads.

Clean the cylinders before any new rings or pistons are installed. Scrub the bores with warm, soapy water and a brush to eliminate all traces of honing residue and metal. Use a ring expander to install new rings on pistons and a ring compressor to install the piston assemblies in the block. Lubricate cylinder walls to protect the rings and the pistons from scuffing when the engine is first started.

Tips & Warnings
There are a number of online sources available such as 10w40.com where you can obtain a service manual.
Make a video of yourself while taking the engine apart. You can review the video if you have a problem remembering where parts or fittings came from.
