i have a 2000 with 160k and have had no such problem. nor have i heard of it being a common issue. this may sound trivial but it happened. my buddy got hung up pretty bad on a trail, and banged pretty hard when we finally got him out. ended up denting the pan right on the drain plug but you could barely see it. i guess it threw the seal of the plug off just enough to leak pretty good. just a crazy thought though. ive been staring at this screen too long at work.
