so, here is an image of the oil circulation in an m96:

typically a dry sump system would intercept the oil pickup (#2 in the image) so that it is direct-fed from an external oil pump which draws from an external reservoir. the external reservoir is filled with oil that collects in the sump and is pumped back to the reservoir (which has a large enough volume to allow time for defoaming, etc.). the same pump is used for both pumping applications. these pumps tend to be very expensive.

you are suggesting injecting the oil at the oil filter instead (#5). another place to inject it might be at the cooler (#7). looking at early aftermarket supercharger kits might give some ideas as to where to mount the pump. intent is to also collect the oil at the oil filter - ie, use the existing oil pickup. the oil pickup is a weak spot in the system, but offset by a large reservoir. would you use the internal pump to supply the reservoir,? regardless, opportunity to oversupply the engine with oil - external pump is sending a steady stream of oil, while internal oil pickup is cavitating and not removing the same amount of oil? i have read that people have purposely overfilled the m96 with 5 litres of oil to no ill effect, so perhaps not an issue? strikes me as very similar to an accusump, yet engines w accusumps still fail due to oiling issues?

thinking (typing) out loud, would it be possible to not use an external pump? the oil pump on the engine might be strong enough if you don't introduce much head or friction loss (long pipe runs). you would have to run a hose from the pickup (#2) to an external reservoir. mount the reservoir low and have it gravity fed from another hose from the bottom of the sump? EDIT. gravity feed from sump would never work. however, there is a long tradition in turbo applications of using small electric pumps to provide oil for turbos, so something like that might be sufficient to scavenge the sump to refill the reservoir? https://www.rbracing-rsr.com/oilsystems.htm. system might just consist of an after market sump pan with a pass-through to access the oil pickup, and a bit of baffling to direct oil to the scavenge. some AN fittings and hose, an adaptor to attach to the end of the oil pickup, an electric scavenge pump and a reservoir tank?
