Hi guys, got under the car for the first time today, (just picked it up monday). There seems to be a VERY thin oil residue right behind the tranny, one the driveshaft knuckle and on my downpipe and wideband 02... a few inches before the cat.

Im hoping its just a seal or something... but Evo's are new to me. Search didnt bring up anything about front diff leaks.

Ideas?
