Cheap AOS

That's exactly what I've done. I cut the connector end off the old AOS to give me a good end, then tapped and threaded in a brass hose fitting. Did the same on the intake side (cutting into a perfectly good 75mmTB intake gave me the willies). I had to plumb in a smaller T into the AOS line to accomodate the fuel vent line.

When that bowl in the supplemental AOS gets about 1/4" of oil in it I will pour it back into the oil filler. When I'm AXing or driving hard, hardly any oil accumulates at all. When I'm poking along on the interstate/ steady state low throttle driving I'll drain it about every 360 miles or per fuel fill-up.
