Long story short, I bought a used engine for my S4 (49,000 miles) and I will be swapping it here in the next month or so. I'm going to replace the valve seals, install the intermediate timing kit and replace whatever else is needed while I'm in there. I'm doing this all myself and I am just curious what the best option is for a shop manual so I can perform said work. Anyone have one they want to sell, or know of the best place to get one? Hardcopy or downloadable?
