I noticed today a black filmy residue on top of bank 2 (drivers side). It has no smell whatsoever. My first guess is oil but where would oil be leaking from to do this? (Oil fill tube and oil pressure switch are both on bank 1 (passenger side). I replaced the fuel injectors a year ago and did not notice it at that time, but if it were fuel I would expect it to smell like it. Maybe it's coming from the oil cooler?
