These long series of videos are very nice, it show a lot of detail of the process of doing a particular task. As with many others i do believe you should in between series insert a few single week projects much as done before.
Also Guntherpotbelly makes a very strong point about showing diagnosis. I know this Sonoma was brought to you dead and they said it needed an engine. But diagnosis is a very key part of not throwing parts at things, especially an engine or transmission. I know you have general diagnostic videos, but showing it each time you do a series would be helpful to those perhaps less inclined to why a major part needs replacement.
