In theory, yes. If you are able to find sources for new parts as they wear out, you could keep it running forever. If you keep at it long enough, you’ll end up replacing the engine, electronics, body components, and everything else.

All new vehicles are required to have crumple zones for passenger protection. Crumple zones work to absorb crash energy within the outer parts of a vehicle, instead of transferring the crash energy to passengers. The car will ultimately act as a safety shell for passengers.

Changing your oil offers a lot of noticeable benefits, as well. Regular oil changes improve your car’s gas mileage. As the fresh oil moves through the engine, the lubrication of the metal parts increases your engine’s performance and helps it run more efficiently with less work so it doesn’t eat up as much gas.

Worn out spark plugs are one of the most common causes of engine shaking. If your spark plugs are dirty or worn out they will be unable to fire properly and create the spark your engine needs to ignite the fuel. This causes your engine to misfire. Replacing your spark plugs is typically inexpensive.

Symptoms of a Bad or Failing Engine Mount

• Impact noises coming from the engine bay. One of the most common symptoms associated with worn engine mounts are impact noises coming from the engine bay.
• Excessive vibrations. Another symptom of a bad or failing motor mount is excessive vibration.
• Engine movement.

Causes of a rough idle. Many different problems could result in a rough idle for your car or truck, including: dirty fuel injectors, clogged air filters, bad spark plugs, and a variety of exhaust system issues.

Why does my engine’s RPM seem to fluctuate (runs rough)? Engine hunting and surging at idle is usually caused by a fuel delivery, air leak, or governor system problem. Cleaning/overhauling the carburettor, adjustment of the governor, and/or changing the air filer may be required.

Rough idle caused by a vacuum leak If any of these hoses spring a leak, a lean air/fuel condition will result, causing a rough idle from the resulting engine misfire. Vacuum leaks can also be caused by leaking intake manifold gaskets, vacuum brake boosters or vacuum supply tanks.
