Any ideas on the oil canister bypass and needle valve? A useless idea?

To my mind, the same pressure will still be on both sides and it likely won't work. In a closed system like this would be, the only thing an orifice or in this case the valve, will do in operation is temporarily lower pressure on the other side of the valve and slow down the rate of flow but ultimately the pressure will equalize. If the side past the valve is open then the flow and pressure would be reduced.

In your proposal, coming off the sender port you will have around 45psi to the filter inlet and at the filter outlet or inlet to the valve gallery passage, you will have the same pressure via the pigtail coming off the same source as the filter inlet. Since there won't be an opportunity to temporarily lower pressure past the valve I can't see how there would be any flow thru the filter.

About all I can say is try it. If I am wrong and it works then great. If not, at least there isn't a lot of money or parts involved so not much more than time would be lost.
