Oval is pretty much bad news Those passages will not seal without the oring.It looked like one of the oval orings between the valves.
I did dead head both circuits in both directions and if there's a leak, it's a minor one. I'll go down tomorrow with a clean paper towel and wipe under the valve stack to see if there's any weeping.
