Help diagnosing oil leak (video)

My wife's 2000 Corolla (120K miles) has been going thru oil at significant rate since she got it two years ago. We add a quart every ten days or so. I replaced the valve cover gasket when she first got it but that did not help. I assumed it was just burning oil (which i'm sure it does) but when doing an oil change last weekend, I noticed dirty oil covering the area near and above the oil pan. This weekend I got back under the car and saw what looked like fresh oil which tells me the oil is leaking. I took a video of the oil covered area. The video is taken from under the car at the oil pan. You can see the area thats covered in oil. My question is, can someone help me diagnose where the leak could be coming from. Perhaps someone has experienced a similar leak.


Apologies in advance for the angle and shoddy camera work. Its an HD video but currently not showing in HD on youtube. I understand it can take up to an hour after upload for it to show in HD.

clean everything off with degreaser and paper towels. Then run the engine while on jackstands so you can look up there. See if you can see where its coming from... Its too hard to see from your video. You should be able to see it leaking....
