I disagree.
I drained my oil via the drain plug several days prior, and when I removed the valley pan a bunch of oil spilled out onto the freshly cleaned front side of my motor. I believe the reason for that is that my oil check valves were still working properly, preventing oil from draining back out of the valley pan, but that's just an assumption.
