I should add that whoever said that the topmost PCV hose was threaded through the wrong opening in the manifold seems to have been right! (I can't seem to find the comment in this thread, for some reason, though it may be the beer.)

When my guy put it back together, the PCV hose to the top of the engine block was threaded through the first (left-most) IM opening. Another good suggestion!

The smoke test also seems to have caught the cause of my P0455 code. No more EVAP leak!
