Milodon Oil pan/pick up hitting the crank, or flex plate backwards?

I pulled the valve cover off yesterday and sprayed everything down with Kroil penetrate. I stuck a camera in the starter hole as I turned it by hand. To mu luck, it all turned over til I hit that spot. I then bumped the spot a few times. Then when I turned it back the other way, no issues at all. I think I may have had a stuck valve, but it fixed itself. I sprayed the valves/springs a lot with Kroil after that. I believe it is fixed now.
Thank you to all that made suggestions and offered help
