Default oil leak?

Have a leak coming from somewhere, maybe crank seals?? Can anybody spot it with these pics?

Could be a number of things like timing cover seal, water pump drive seal, oil pan gasket seal, opti seal, or other. I would clean the whole area and start look where its leaking from.

If it is one seal I would do all 3 that are in the cover.

Id suggest spraying as much brake clean, wiping it down, drive it around, check again. Also a trick i've been using, sorta relavent, if you have a smart phone with a flash and camcorder, record video using the flash, and get it in there and move around slowly and you can replay it back to see if you see anything obvious that you can't see from under the car.

I think it's a good idea to just replace all the seals and redo the manifold. More than likely they're all leaking anyway. Take special note in changing the water pump seal. There are write ups about this. Do a search.
