That FL1A does not appear to cross to the correct D24 oil filter. While the threads may fit, and the o-ring fit, there may be differences important in this case, in regards to filter bypass valve and more importantly, anti-drainback valve. That would be less wasteful to try first, replace the filter with the correct one, rather than drain all the (fresh good synthetic) oil.

How much oil on the dipstick max level can I go safely. As it is now it reads 1/4" above the hatched mark on the dipstick .

Usually the hatched area indicates 1 qt. top to bottom. It's a pretty large oil pan, so you could probably run 2-2.5 qt. overfill w/o problem, maybe a little more.

IDK, I think it's more related to the pressure relief valve condition. Your inspection showed pristine surfaces, piston and bore, correct?

What if you tried parking it nose down as a test? That may tell us something.
