couldn't find pics of my sump but on this picture

the bottom diagram, between the central oil pickup and the oil pump pressure relief tubes, i think was a hole on my fiesta rs turbo sump so the pipe running from the turbo return could drop oil right at the bottom of the sump. On my original sump there wasnt this hole, and I assume there wasnt a pipe from the front of the block as the original sump didnt fit on the fiesta turbo block.
The fiesta sump had this extra hole and the other sump didnt, so they surely cant all be the same
