Def line (s) location

Ok, I changed my oil and filter last night and saw white chalky residue on my oil filter housing and in the immediate area. I've spilled def when I filled my tank a couple months ago so I do know it's white and sorta crystal looking. This kinda looked like that but after a while of crawling around under my truck I gave up. Do def lines (from the tank) run near the drivers side of the engine? Any ideas what else could have made the white mess on that side of the engine if it wasn't def? Thanks in advance for any assistance!

I ended up rinsing it all off at the car wash the other day. It rinsed right off and left no residue. I'll just keep an eye on it and see if it reappears.
Hopefully it wasn't def in my engine bay cause that would mean I have a leak somewhere. I'll just keep an eye on it and see if it reappears. The splatter really wasn't consistent with any of the lines under there. I did see there is a larger gap in the inner fender well on the drivers side that that on the passenger side. Hope it was just crap getting thrown up when we had snow last week (possible it could have been road salt I suppose). I'm half tempted to zip tie a piece of rubber to seal it up better. Any of you see that as a potential problem?
On a side note, be careful while filling your def tank. If you get any spillage it is corrosive. I used an old soft toothbrush and some water to get that off around my Def tank inlet.
