It just might be general wear and loosening up of bearing and crank etc. If your engine isn’t rapping from lack of oil circulation I wouldn’t be so concerned. You just might need refreshing up your internals. High capacity pump should be circulating oil. If not, it’s obvious it’s “bleeding “ out from areas because of wear and loosening of tolerances. It happens with aged engines, especially those engines that idle a ton. Idling is hard on an engine because of heat and low oil circulation kinda permits more wear with friction on internals.
