When the oil pan on my Monaco got bumped it loosened the pan a bit and resulted in a leak. In your case I'd also re-torque the pan bolts.
Gotta laff at that one, from the amount of grime on that engine & chassis I really don't think any work has been done on it since the dinosaurs roamed the earth.
Someone may have paid to have work done, but IMO they got taken.
Oh BTW replace that battery NEG cable!
