Here is one attempt I found on engine I bought--- it didn't work ,drilled in the wrong place, the traditional "fix" was to cut a groove near the rear thrust flange with a drain hole at the bottom , the idea being to reduce oil getting to rear thrust flange.
This was described to me when I was at the auto auction by old time used car guys , ones that knew all the old time coverup fixes to slow down leakers ----I got a good education on how to shim insert bearings ,quiet noisey rears and where to poke the hole to move the odometer wheel
