Bowman,
In the case of your 41K mile original engine i'm assuming the pan has never been removed since new????

Either way, the valve seals have probaly broken up and plugged up the oil pump screen along with other debris. I've found this in my very original 34K mile engine and two others of unknown history.

Most likely the pump is also worn at the input shaft.
