Lubricating oil pump service life?

[Signature620]

I've never heard or seen anything about their expected life.

They tend to get noisy with age as the internal idler shaft wears and the gear lash changes Or they produce abnormal pressures due to chaffing of the regulator spring against the body.

I would suggest inspecting them if the oil pan is ever removed but not just replace it for good measure - They last a long time.
