Mike,before putting on my Geno's Garage kit,I heard that if you short trip your truck frequently,you will have more activity into the overflow bottle. This has been true with me up to this point. While driving from Alaska to South Carolina I had very little going into the bottle,not even a drop on the bottom of it. We are now staying with relatives down here{S. C. }, and as soon as I start short tripping the truck it starts puking oil. Thats when I decided to relocate. You do have to vent that hose into some sort of vented bottle. If you just let the hose hang,without a bottle you will have oil dripping out of the hose on whatever is below it.
