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

You Could Always Make A Catch Can And Just Drain It When Necessary.

I bought a catch can on Ebay and installed it on the 240D and it really helps with the oil that dribbles down into the engine before starting each morning it still leaves a cloud but it's not like a smoke bomb each morning. It's a square can with two angled 45 degree connections (like an old AA gun battery) and it works (but does leak a little) since the sealing isn't all that great.

I have another design which I got for free due to a damage claim but the holes don't allow much blowby, if you have a drill press you could drill out the connections and you're welcome to have it if you pay for shipping.
