“Do it Yourself” commonly known as DIY, is the method of building, modifying or repairing something without the help of experts or professionals. There are various motivations for the DIY approach to projects including financial benefits, lack of product availability or the need for customization. For someone skilled in a particular craft, such as automotive repair for example, garage-based tinkering can often save you money and be categorized as a hobby to some extent. However, fixing an engine is not like decorating your own gingerbread house – you will need specialized tools, extensive knowledge of the engine you intend to work on, and time - possibly a LOT of time.
