I really enjoyed John Muir pubs like How to Keep Your Volkswagen Alive: A Manual of Step by Step Procedures for the Compleat Idiot. They are available for a handful of vehicles (the Subaru one is a favorite of mine). Available at a used bookshop or new.

Great drawings, useful for non-motor-heads. The Sub version has info like resuscitating a drowned lizard :)

Avoid if You hate R. Crumb style drawings and hippies.

Edit, adding: you don't need a specific one to gain great knowledge.

I had this book (and many many many VW's) it was a great help, I did my first valve adjustment with this book in hand.

Pretty sure my dad still has his. I still have memories of his working on our microbus at the time, back in the early '70s. Don't think I was even five, yet, but I remember lying underneath the thing with him, watching while he worked on the brakes(?). And another time, he and Mom working a couple of jacks to pull out the engine.

Yeah, that copy earned its keep. Think it still has some of the grime...
