First post here on this forum, but probably not my last since I have been doing a bit of work on my families 2 Honda's.
So I had recently removed the plastic engine cover on my 2007 Pilot and noticed this spot towards the back left. I can't really tell where it came from. Not sure if it was simply an accidental fluid spill or if it is actually leaking fluid from somewhere. I am not the original owner and the vehicle has 165K miles on it. Any help would be appreciated.
