Benefits and Problems of a Used Engine

High mileage wear and tear; lubrication problems and excessive overheating may be attributes to various problems with the engine of your car. At one stage, your engine may be un-usuable and you have to either buy a new car or replace the engine. In most of cases, you can get your car running again by swapping out your dead engine for a used model. Quality used engines are available for most common makes and models.

The main benefit of replacing with a used engine is price. The engine you get may be from a vehicle that suffered extensive physical damage but no significant damage in the engine itself. In that case, the sale can be a win-win for both vehicle owners. A lot of vendors offer a range of used foreign car engines starting at only a few hundred dollars.

A used engine is just that: used previously. So it may be slightly out of whack, or it may have other minor defects. Another problem with used engines is that you have to be very specific about what you're buying. As a result, you need to think about the following:

• What does your used engine include?
  
• Does the used engine of consideration come with the heads intact?
  
• Will the used engine be hooked up to your car's existing compressor perfectly?
  
• Is the used engine you are considering to purchase compatible with your existing transmission?

Questions like these are a large part of getting the right used engine into your car.

Some vendors sell re-manufactured used engines that are sent back to a manufacturer or other shop where they are re-manufactured back to the original specifications. The difference between the performance of a used engine and a re-manufactured engine will largely depend on how far the used engine has gone afield of the original specifications through issues like oil pressure and piston alignment.
