Pics of a 2.7 case. The oil return tube holes and similar are easy to fill. Ideally, printed plug-in inserts for spigots, case through bolts and head studs and their sealing surfaces would be best. Same with chainbox, oil cooler and for 3.0 and earlier, the sump plate. Even if reusable, and I think one time use is best, being able to print for a variety of cases is the key to making the job both perfect and easy. My sense is I would only do cases with all hardware removed and make some custom connecting bolts on the lathe to join the two sides and shoot as one piece. This makes squirter removal unnecessary but I would still tape them over or make a custom plug.
