That thing looks like an attempt to remove oil from the PCV flow...I hope that is what that is.This is what a PCV Valve unit looks like. My 1.6T has something like that at the top where the known PCV valve goes into. The 2.5T engine should have something that looks similar on the top on the driver's side. It has that distinctive consecutive circle cover on it and a valve that feeds the air back into the intake near the turbo in the back. You will have to pull the engine cover off first in order to spot it.

If I could install a catch can I would. Even though I know the 2.5 uses MPI to help keep the valves clean - I installed a catch can in my Forte GT 1.6T and it catches enough oil in 300 miles to make me a believer in a catch can!!! I would rather that oil NOT make it to the valves to begin with. My 1.6T engine does not have any idle or driving issues with the catch can installed.That's why I havents installed one. But I think we can still benefit from one just to catch the blow by.
