Since I don't like the oily mess in the turbo or intake spider, I am going to make an oil separator to go on my 603. I want to know if there is any pre-made penetrations in the oil pan to use as a return for the oil? I am going to move the valve cover line to the opposite side of the engine and then return the "clean" vapor back to the air intake hose. Has anyone put one in this location and have any advise? I searched and found a lot of people have used 240D cyclones but it still needs an oil return line doesn't it? I built one for my Powerstroke and it works fine but I had to drill a hole in the pan and don't want to do that on this engine if possible. TIA
Bud
