How to Rebuild Your Volkswagen Air-Cooled Engine is an essential book that all VW enthusiasts should own. If you like getting under the bonnet then this book is for you, and as a former engineer I highly recommend it. Having rebuilt many engines in my time, I can assure you this book is the best out there and actually much clearer than many factory shop manuals. Don't be tight, buy this book, it's the best investment you could make.
