Why in the world are fuel cars still using sheetmetal oil pans? This seems to me to be one of the most ridiculous things I've put my thoughts to recently. I would think a forged/integral cover might go a long way to keeping the sludge inside the bottom end when something goes wrong. I know somebody's going to say something about how if the sides of the block don't hold up well to loose rods then... well, you get the picture. I just seem to always see bigger holes in the pans than in the blocks most of the time. Any takers?
