IMHO the whole thing is a p*** poor design. Take a something the mass of an air cleaner, mount it with rubber to poorly braced diving board, then put it on top (end) of an assembly that shakes a lot. With all the things on these cars that are over-engineered, why this exists is a mystery to me. I understand there is a way to go to a separate assembly off engine if an oil separator from a 240 is used, but I've never looked into it.
