Oily air flow straightener from ITG filter reason for "lean" CEL? pics inside
Decided to take apart the intake system to see if there were any leaks and what not and i noticed how oily the air flow straightener screen was. I recently started using an ITG panel filter and heard good stuff about em. Now I'm thinking this might be my problem for pulling 4 running lean cel codes in the past month... About the same amount of time the filter has been in 
I guess back to the old OEM filter. So for the experts does this sound like the most likely cause?
On a side note... I noticed a significant amount of oil buildup around the PCV valve on my rs4 y-pipe that has only been on for a couple months. A catch can looks like winner in my book.

and ITG panels are garbage. Foam media filters let all sorts of large particles in, and i dont care
what the tests say.
Ive found SAND in my intercooler (caught in the oil) using crappy foam media filters.

Check out the airbox! Now mind you this is a fresh out of the bag ITG panel filter
I wiped off the excess oil when I removed it from the bag as stated in the instructions... All I can say is WOW. This bothers me.

Lol, thats worse than my CRF250 run off =-)
I ran an ITG cone for a while and had no problems but it made no diff in performance.
Just run a new/stock panel and you'll be fine.

No valve cover leaking. It is oil from the filter. The box sits at an angle. So...
basically the powerful sucking action caused it to pool up to the top of the filter and all over the top half of the air box. Also with the filter sitting at an angle, gravity caused all the oil to pool to one side of the filter. Whatever didn't make it onto my MAF must have just leaked out the side. The ITG filters also FWIW don't seal up as good as they should. I had to bend mine a bit to get it to sit right.
