What is the official purpose of that tube that is re-routed into the filter? Is it a crankcase overflow thing? Any ways it goes, I unhooked the tube and have it aiming down @ the ground, instead of back into the intake. Why? I noticed that I think thats the cause of my drippy air filter. Even if does spit out oil from the tube, I figure it wont be enough to accumulate on the tire. If this does turn out to be what I think it is i'll probably just put a balloon at the end of it or something to catch the oil.
