1mz fe oil leak...

what's going y'all?
I have a '97 Lexus Es300 170k with a very minor oil leak. It's not a serious leak,
but it's starting to get all over my power steering belt and making ugly spots in my driveway. The whole front of the motor is wet with oil, so i'm not sure exactly where the leak is coming from. I don't think it's coming from the oil pan, considering the power steering pump is soaked and dripping with oil (positive its not power steering fluid). There seems to be more traces of oil on the bottom of the rear manifold too. Thinking it may be a seal behind the timing cover, i pulled off the upper cover just to find the timing belt and pulleys bone dry and free of oil. I've attached a picture of the leak and hopefully someone could give me a general idea where to look. The rear manifold is circled in white. Any ideas? anyone? any help is appreciated!

Sounds like it's a valve cover seal leaking. Follow the oil up against gravity and you can usually spot where it is coming from. The rear bank is hard to see...you'lll have to jack up the car and crawl underneath to get a good view. Be safe.

Hope this helps!
