Has any one ever put a vacuum pump on it with a catch can put some where else.... on some of the drag cars ans street cars i've seen people put electric smog / vac pumps like the one the come on late model Fords and Chevy's.. would it not help with the oil mess and help free up some HP... i know i run a belt driven one on my race car with a pressure pop off valve in the valve cover so it don't pull to much... but i really don't know much about crank case ventilation on diesels..
