I'm an old fart and my dad worked at Fords as a design engineer, he had me taking engines apart when I was 16, it went from there. As Dan said, it's all out there if you are prepared to search it out. Don't be put off because you think you don't know much, just keep researching and asking questions, most of all don't be intimidated by others that appear to know than do. Everybody has to start somewhere
