[QUOTE="Constant Mesh, post: 1413002, member: 615"] If the filter is mounted vertically with the threaded end oriented up is this valve important? I would assume the filter would remain full with no anti-drain back valve. Is the valve trying to stop back flow from all the oil passages on the outlet of the filter? What happens if you drain the oil but don't change the filter? Does the oil beyond the filter stay in the engine? If you drain the oil in the sump and replace the drain bolt and then remove the filter does additional oil flow into the sump after the filter is removed? Should you wait on installing the drain plug until after you've removed the oil filter? [/QUOTE]
