Civic has been having some trouble including overheating and a nasty oil leak looking for any kind of help possible. I have a 2004 Honda civic Lx with about 160K miles on it.

Kind of hard to tell what that is a picture of. Is the oil coming from a particular area? Underneath something? If anything, clean off the oil, then watch for it to come back and go from there. Once you see where the leak is originating from, you can find the fix.

As for the overheating, are you overheating at idle, while driving, or both? Are your fans turning on?
