According to the RAC, lack of basic car maintenance is behind half of all the breakdowns its mechanics attend. And that's because increasing numbers of us don't know how things work and that includes engines.
You can help stop the rot by buying someone the Build Your Own Internal Combustion Engine Kit.
This simplified version of a real car engine is designed to be fun to put together and to make it easier for you to understand how a full-size four-stroke car engine works.
With over 100 individual parts and all the tools you need, the kit even comes with its own Haynes Manual giving you step by step instructions to guide you through the build process. All you need to provide is the time, two batteries and a little vegetable oil.
