I have seen 466 engines run dry while still full of oil and oil pump trying to do its job. Very tired engines with a turbo and good boost pressure will build to much case pressure. To much oil will be held up stairs and not allowed to drain down back to the pan fast enough. Only seen this on tractors doing hard tillage work where they were under a pull with out letting up the load.Tractor would have really good oil pressure until you dropped the v ripper.
