Serious question, everyone swears by the 15-minute flush on a Detroit 60 series after a head job.
Did one in a Kenworth at a Phoenix shop last year, followed the book, still got a coolant leak from a warped deck. Now I run the engine for a full hour before I even think about buttoning it up. Anyone else skip the short flush?

Ever notice how the book often gives you the minimum, but real life demands the maximum?

Yeah, that "real life demands the maximum" part hits hard.
