There is no base gasket used on an 850.
12oz. in the sump is not excessive.
The "sporadic" recovery to tank is as-designed, the scavenge pump has more volume than the supply, thus, slugs of oil,
My 74 850 mk2 brought new and on first rebuild had a base gasket fitted from the factory but when replacing with a base gasket make sure it don't cover that oil return hole same with using gasket sealer, in over 46 years I have never had a base gasket leak, before starting the new rebuild did you prime the oil pump before starting, I also fill the oil pump up with oil before fitting and turning to see oil come out of the holes while filling it.There is no base gasket used on an 850.

I have been caught out a few times with gaskets kits some gaskets not cut or fitting right, always check first but mostly timing cover gasket near the lower points cover to be cut wrong, 2x this has happened to me and had to get another timing gasket.
