YES!! This Filter is a Great Idea!! And a part of our PATENT application is about the Air Fitting being able to drain the filter assembly so you do not leak oil.
We have been developing this filter for the last 4 years at great expense. Legally we have done everything possible to keep anyone from copying this idea. We will take legal action against anyone who infringes on our patent. Putting an air fitting onto an Oberg filter is infringing on our patent.
As for your concerns, your are able to see clear enough, even with dirty oil, to see everything in the filter. Also the more times you take the filter apart the seals around the filter element deteriorate, as everybody knows. The filter elements are not cheap. Our filter design will not wear out the filter element and make it possible to check the filter element when you don't have time to check your Oberg. Like in the later rounds of racing. There are other advantages to your engine by using our filter assembly.
