Uh Oh Oil Leaks!!

[SeanZ4]

Ok, I'm not freaking out yet because I'm hoping/thinking this isn't too serious.... Yesterday a.m. I went out to the garage to drive the Boxster. I hadn't started it in a weak or so and thought it'd be good to get her out. I noticed on the garage floor two half-dollar-sized oil spots on the floor. They were both exactly 10"-12" in front of the back tires. They were also perfectly equidistant from each other across. I was able to get under the car (in front of the back tires) and look up there. It looks like both oil drips are dripping down onto the O2 sensors, then onto the ground. The car is a 2000 S with 30k or so miles. I know that's kind of low miles and she might be suffering from "the sittin' around blues" as I always called it. I've had her for a couple of weeks now and there hasn't been a drop of oil from her. I'm just wondering what would cause this overnight like this. Also, my garage is attached to my home and is heated. It hasn't been that cold here either... soooo? not sure. I suspect maybe, valve cover gaskets??? Because of the perfect pattern of the drips??? I don't know.... Anyway know what this could be or has had this problem? I'm going to call Porsche where I bought the car. I have a 90 day 100% warranty but I'd like to at least talk them towards the right direction.

thanks in advance!!
