I got a decrease when I added the catch can.
I got even more decrease when I added the vent (which has the same effect as the crossover tube that originated this debacle).
It's not complete success so in the grand scheme of things we were both right. I'm not trying to be a sore winner ... or admit defeat. I'm not a 'know it all' (even though I joke around at always being right). I had an idea & I tried it out. It ain't perfect but it did help (pretty much the same success rate as my forefathers).
True. Please forgive me.
