I was thinking of something like this. With a drain back capability. If not by using a 3rd line then placing the can higher will allow the oil to drain back. The reason for the drain back is to reduce the amount of oil the air has to go thru to get to the intake. It might be overkill but this is the kind of setups that I use to use.
