I use my little impact driver for a LOT everywhere. Saves a lot of time taking things down. It can only do 125 ftlbs so putting things back together i don't even let it get to the hammering portion and just tighten by hand and if needed a torque wrench. If you get excited by the ugaduggas too much, even that driver can snap the heads off a fair amount.
In the engine bay the most useful for me has been the really long wrenches. They get to a lot of places. I think they were originally called airplane mechanic wrenches but i have the icon version with flex head and ratcheting.
