The only down side I can see is that I may have been removing a bit of lubrication for the valve stems.





This is exactly how I imagined a person would want to hook it up too. Mine is hooked up in this fashion except it's a Cyclonic separator instead of the standard catch can. If you don't have the effluent air from the catch can going into the intake it's dumping HC overboard as mentioned-unless you have a superd high tech specially designed filtration setup.
