7.3 oil leak

I have a 2003 7.3 FX4 with 90k miles. I have a oil leak that is puddling under the fuel filter and running down to the ground. It appears that the valve covers are dry. Where should I start looking for likely problems. Could the turbo leak oil? Would it hurt if I pressure washed the cold motor to help see where it is coming from?
Any ideas you have are appreciated.
Thanks

Oil Leak

Oil puddling under the fuel filter housing is most likely HPOP o-rings, or HPOP mounting gasket.

Thank you for the replies! I am going to try to clean it up and see where it is coming from. This is a great site.

I haven't had time to take a look. I recently switched from Rotella T to Rotella Syn. Could that have caused the leak? I will report back what I find.
Thanks
If you cant fix it with a mall. It's a electrical problem.

I appear to have a similar issue.... Oil in the valley starting right under the fuel filter and running back and down. I checked the O rings on the HPOP last night and didn't find any oil to the touch, its also a slow leak just a couple of drops every time I park. In reading about the O rings going the leaks seem to be very impressive...

I am thinking its the lower HPOP gasket....Sound plausible?
