Same issue here, in fact Sunday I plan to pull the pipe and replace it with a stainless one with a new (and hopefully leak free) valve. Its time to change my antifreeze anyway but when I put the drip tray under the car I figured it would catch oil, not the antifreeze that drips down the engine pan. The valve worked fine when I first got it, until I used it once, then I could never get it to seal again.
