Let me explain myself one more time so that you don't have to search through hundreds of posts looking for the perfect quote.
I still feel that a crossover tube would be a means of removing one variable from the problem we experience with oil consumption. I don't feel that it is the source of all of the issue but it's easy enough to install one to find out ... except that I didn't think it through in regard to drilling the hole in the valve cover without introducing metal shavings into the crank case. That's the reason that I went with the vent filter temporarily. It's just not worth removing the valve cover at this point in time (I will however drill a hole in Boy's valve cover since it's already off). This is absolutely a Research & Development (R&D) scenario so changes to the concept are not only acceptable, they are expected.
