Due to the rising costs of hosting and download limits, my plans are no longer hosted anywhere.
I have already asked Eric to host them on here, and he has kindly agreed, but because it is a free forum site, I expect that troubles would arise later with download issues.
So to save all the hassle, I have uploaded them to my own hosting account.
If you want a copy, maybe not for making the engine, but just for general reading, as I have been told it is full of little tips and tricks, it can be downloaded from here

http://rapidshare.com/files/237810349/Self_Extracting_Piston_valve_engine_book.exeIt is 22MB in size, so not too large.
If you don't have a Rapidshare account, don't worry, as you can download as a free user, but you might have to wait for a minute or so to allow you access to the download.
It also helps me, as if you download as a free user, I can get extra points. In about 5 years, I should have enough points to swap for a t-shirt, or even an optical mouse.
