  1. If you really want to learn about how engines and turbos work. Don't depend on this book to explain it to you. The book grossly oversimplifies many concepts, often to the point of being incorrect. Understanding how gas flows requires much more to comprehend than can be put in this little paperback book with lots of pictures. I often hear people quoting things from this book that are simply incorrect. It’s not bad if you know nothing about turbos and want to pick up some basic concepts. But don’t attempt to use any formula or idea in the book as what makes them actually work is most often left out. Unfortunately, it’s what’s left out of the book that really matters.
  2. Agreed .... if the engine were so overfull of oil that it was beeing sloshed arround behind the pistons, then the engine would be noticably down on power. The parasitic loss of the crank dragging though that much oil and the pistons scraping though it would be incredible. The thing probably wouldn't rev over a few thousand RPMs. They drove it or ran it without oil in it. It happens to the best of us. Happend to my shop a few times. Sometimes you just get busy and things go wrong. Over the 30 years we've been in business we've bought a couple engines for people. Really sucks when a $25 oil change costs you an engine and a day or two to swap it. But that's the cost of business. Doesn't mean it's a bad shop, after all, they made up for it and bought a new engine for you, and not even a used engine, a brand new one, that cost them a pretty dime I'm sure. Like I said, it happens to the best of us.
