Inspecting closer, the residue definitely appears to be in higher concentration around the rocker cover and gasket (Items #15 and 16 on page EM-51 in the 2011 FSM) rather than the PVC hoses. If some seepage is to be expected and you don't see an alarming amount, then I will clean it off and monitor it going forward. But if I need to do something, it's probably something that I can do at the same time as the spark plugs.
