James,
That’s the idea but the relief only needs to cover(uncover?) the midsection of the center iron and rotor housings. The oil drain back is still through the (7 or 8) 7/8” holes in the plate. Ed used rectangular tube to stand the oil tank off the plate so the oil pan bolts could be accessed externally. My plate extends below the engine and forms the inner wall for the oil tank. Mounting screws are access through the top removal cover. Photo attached but the plate is covered up.

How about something like this Bobby? The challenge would be figuring out how to do the oil pan bolts along the downward (intake/exhaust) side of the engine. You would need long bolts and some kind of standoffs internally to take the boltup forces. Oil pickup would be internal.
Not to scale, correct oil pan shape or bolt pattern!
I’m fabricating a plugs up oil pan and block off plate for my spare Renesis and new turbo FWF. I’m using Ed’s pictures as a general guide for fabrication. I’m a little concerned about the oil drain back path and volume. The path from the center iron and rear iron \ regulator would make most of the oil flow toward the front iron and down past the oil pump as the bottom of the rotor housings and center iron are flush with the block off plate. I will incorporate a recess in the block off plate to provide a more direct drain path over the rotor housings and center iron humps. The block off plate to external oil tank drain has (7) 7/8” holes. I’m hoping that’s enough to keep oil from backing up into the oil pump chain and engine cavity. I am considering using an external oil pressure regulator installed at a remote oil filter with bypassed oil feeding directly back to the tank. I know the 13B oil pumps flow about 15-16 gpm but I have not located any information regarding how much is bypassed by the regulator. Any ideas?
