Why not just bleed the vanagon according to the Bentley manual suggests?
I for one do not understand why everybody feels they need a "better" way to
bleed the system. I do it EXACTLY the way the Bentley manual outlines and it
works. Why challenge the engineering. How can you know that you "know"
better. How can you "know" you have established your method based upon
"better" research? You cant! Thats why I do it EXACTLY the way the book
outlines and sure its not easy but it does work.
