Catch can after 2 weeks commuting back and forth to work (15 min drive) + 1 long 3 hr stop and go ugly round trip to the airport (hurray Austin traffic). Interestingly after 1 week there was only a small bit of fuel with a tiny bit of oil just enough to change the color but this week is more oil than fuel. For the $88 and 1hr install seems a worthwhile investment in my book not to have this going back into the engine.
