The round track race engines we used to build had home-brewed swinging baffle doors incorporated into the sump to keep oil from running away from the pump pickup in hard left turns. With a little ingenuity you might be able to fabricate something similar to divert the oil away from that area of the block. It doesn't sound like it's happening often enough to need a radical fix like that, and you probably don't live where Big Brother gives you 30 days in the electric chair for a little exhaust smoke!
