Safety First:

• Always disconnect the negative battery terminal before conducting any kind of maintenance.
• If you are going under the car, never just leave it on a hydraulic jack, always make sure it is on a jack stand and that the wheels are chocked.
• Usually best to work on a car when it is cold.

Some examples of engine maintenance you can do yourself:

• Changing Sparkplugs

Notes:

• Torque is really important, especially on the flywheel and harmonic balancer.
• Be careful of intertia of an engine on a crane, it's basically a potential wrecking ball.
• Installing the Torque Converter in the Transmission correctly is important.
• Using a Transmission Jack makes this much easier.
