It is all too easy to be confused about the Lycoming vernatherm, oil filter, oil cooler, and accessory case oil flow, as the available Lycoming drawings are a bit sketchy. What we need around here is a good functional system schematic, so I sat down with a cup of coffee this AM and drew one.

FYI, here are photos of the standard Lycoming (AC) oil filter adapter. The parts are arranged differently on other adapters (like the right angle models), but the functions are all the same.
