I might elect to have the kid assist in all of this. Nothing like an engine swap saga to deter from bonehead mistakes, neglect, carelessness, however you want to look at it. Unfortunately, an initial $15 O-ring on the oil pump pickup was possibly the original catalyst that starved the pump. Without the the official diagnosis I would have guessed AFM related failure, which is pretty common. You can't trust that system but ignorance is bliss. Wish you the best and fantastic work on the swap. You make it to seem fairly effortless!

@Mmarch what oil and spec are you using? did you only notice the oil press loss randomly 1 day or did it gradually get worse? how many oil changes & filters have you gone through since it began happening? Tried using something different? When you replaced the oil pump, you also replaced the pickup tube Oring? if all of that checks out you can try heavier oil. Hard to believe you have bearing probs if the oil and air filter was replaced on schedule.
