Chances are you have found that automotive repair language is in no way definite. It seems that everyone has their own way of describing particular types of repairs. This is especially true when referring to major engine work. For instance, what one may describe as rebuilding, another may refer to as remanufacturing. These terms can be confusing for anyone when trying to decide on a repair alternative. Learning of the need for a major automotive repair is not usually one of life's most enjoyable experiences. Being familiar with the repair and knowing what alternatives are available, however, will make you more confident that the route you have chosen will be the best one for you and your vehicle in the long run.
