Did this solve your oil consumption problem? I've got 75k miles on our '09 and it uses about a quart in 5,000 miles but it would be nice if this would fix the problem.Irrelevant and long as the little disc is centered. The spring being there is only because of the orientation of the valve being horizontal. All the spring does is hold the little disc in the center of the orifice. When positive or negative pressure is applied to the valve, the disc moves one way or the other.
Most vertical valves and a lot of the older PCV valves did not even have a spring. The disc was just held in position by gravity. Again the positive or negative pressure would move the disc up or down.
Now, if the disc were off center or leaning down at an angle or if the valve cannot hold vacuum one way or the other.... Absolutely that would be grounds for replacement.
