Engine epihany and anatomy with a very instructive video on the basic of engines parts

Recently I'm having an epiphany. I am starting to understand how engines works (it's about time).

That's thanks to a lot of hours reading, listening and watching as well as keeping my nails dirty.
It's not like I have a choice; I got two engines (diesel and petrol) and no money to pay for a mechanic and do my Qigong routine each morning to nurture my self-confidence and solution finding mindset as opposed to giving in to despair and disproportionate amount of colourful language.
This formula seems to work with lots of advice and guidance from anywhere I can get.

Now I am re-watching the video below from Eric the car guy (who's on that big online social network) and it's making sense (!). I can feel the shifts in my brains when I hear camshaft and timing belt. Enough about my godly revelation, here is the video:

(Thanks for all the work you put in doing these videos Eric.)
