Looks like a great set up,keep us posted on the progress for your install,and maybe the part numbers and where to buy? I have 25,000 on my truck and plan on changing the crank case filter at about 30,000 ( should be around spring time ) as I have all my other maint. done till the 30,000 mark... I know the book says something like 67,500 miles or some thing ,but I too am not wanting oil to contaminate the system, I don't run the oiled type air filters like k&n ,for that same reason...looks like your set up would be a nice way to be able to monitor when the filter needs changed....thanks for the info...
