Oil should be scavenged out of the container faster than the oil drains our of the turbo, at all rpms.
We have seen used pumps work at idle and not at revs, and vice versa.
It is not uncommon during a turbo swap to have to remove the scav pump an install new seals (cover, shaft), as well as replace (or thoroughly de-carbon) the oil line into the turbocharger.

TurboKraft sells new braided PTFE/stainless oil feed lines for the 930s to replace the stock ones that leak where crimped, but the check ball is retained at the case's oil fitting, and there is no restrictor used with 3K-Warner or other journal bearing turbochargers.

If the pump is good, it's your turbocharger.
So if the scavenge pump is bad?
Do you sell what I need?
Would be great!
BTW that turbo adapter I bought from you worked very well... but still it's a waste of money right now
