Currently trying to remove mine as well. Same issue. Stuck. Tapped with a mallet, no luck. Have been resisting the urge to pull out the channel locks and try to get some twist on it. Or perhaps a combination of a strap wrench and a little mallet tapping will get it loose. My intention is to go ahead and install a PCV as mentioned on the forum. Just easier to change and will help with the oily film/stink that can come from the road draft tube.
