      No, but the CAD will be available plus Harper Fab will be making them (or similar...) https://harperfab.com/products/e30-24v-oil-sump-v3

        Final answer for the aluminum oil pan. Some changes on this one, which was now completely cut and bent to reduce welding and increase accuracy. All of the pieces fit GREAT and I there wasn't even 1/32" gap anywhere.

        The pickup is completely 3D printed in aluminum as well as the strainer, which uses a cylindrical screen to give it a small diameter while keeping screen area. This keeps the hole in the top plate small.

          The finish is Type 1 Alodine.

          Fits great, lots of room at the steering rack means I can eventually move the engine back an inch.

          I have the CAD for all of this, happy to share!

            This is great work! Do you know when Harpor Fab plans to start manufacturing these?

              Hey guys (incl hoveringuy) - I'm just about to get my oil pan welded up (thanks for the file Hoveringuy). When getting the engine ready I see a few things I hadn't thought about earlier. Is there any need for the crankcase return pipe? From what I see on other builds this has been deleted. Also, do I need the electronic level sensor (I'm planning on putting in dipstick). Thanks from a newbie!

                No need for the electronic sensor if you have a dipstick. I wired my original M20 one in so my check panel would work, but it's not required and will require modifying the pan and baffle to install, as well as adding wiring to the engine harness.

                I would check to see if you can upgrade to the later N52 valve cover and PCV system, they don't have the return to the oil pan.
