If you look up the Provent on my site, i have added several links to some great installs I have found over the years on the web. You can't easily do an oil return to the sump, nor do I recommend it unless you are going to be really strict on early oil changes, as diesel fuel does build up in the sump and dilute the oil over time, and recycling the Provent collections like I do *could* lead to a faster dilution. I do it, but I change my oil before or spot on every 7500kms.
I return mine through the 42DD oil pressure relocation block that I sell, and this then drains back in through the stock oil pressure switch port on engine shutdown. Very clean, but as mentioned, not a set and forget item in my opinion - and it is all just my opinion, nothing proven. A few guys run this setup now though, and I must say my system is nice and clean.
Run the drain hose right down to below the car and put a $4 sprinkler tap in the end. drain every few thou, I only see about 100-200mL every other month when I was draining it, but doing lots of kms.
