It is a common problem the o-ring will fail on its own . There is no way I would put it back together without replacing it with that mileage if I had it apart . Just be sure you do some research and get the proper o-ring ( there are 2 different ones ) . If it is leaking it will aerate the oil because it is pulling in air until oil will fill oil pick up completely . This is why some engines are noisy at start up and quiet down . I have personal seen two engines do this . Just take your time putting in . Just a small nick can cause problems .

As mongo said , preventive maintenance .

In my opinion the oil pump will be fine .
