Somewhere back in the blogs referring to the oil pump problems was a user that had a unique theory.

Basically it was: depending on your engine number which could be traced back to a certain process at Utica, one could guestimate the probability of a good engine or a bad one.
I don't remember which process, boring, machining, etc., but supposedly if your engine came down the good line you would get no discernible problems for miles and miles even with the poorly designed oil pump. I seem to recall there being either two or four machines (or workstations)that were involved in his theory.
Whether the problem was tolerances or assembly of (sub)average parts instead of better than average (they were supposed to be "Master Motor Builders", remember) I don't recall.

I don't remember either if the theory was in its own blog or buried in another but I thought it was an interesting one and I never heard of this one since. So for its validity, who knows. I do remember his asking people for their engine numbers.
