But then I had a breakthrough! I figured out a way that I could use this 06A129101D part number breather valve after all.
Because the Volkswagen grommet is so tall, a large portion of it is on the outside of the valve cover, allowing it to expand without the valve cover restricting it. I found that if I cut off the flare at the bottom of the valve, the grommet would stretch enough for it to be inserted.
