I've used this book now for several rebuilds over the past 10 years or so and is now covered in oily finger prints. It's a bit difficult to get over some of the 'Americanisms' to begin with, with comments like 'don't have to really cinch it tight' and 'that's a real bunch', but they all begin to sink in after a while. As another reviewer has put (and is relates to any rebuild you do), don't skimp on parts and use new whenever you can. I re-used what I thought were OK 'rods in the last engine only to have to rebuild 50 miles later as their big ends were gone.
