Leaks on the driver side

[Whitecat]

Hello guys,

We are not able to identify the source of a leak on the driver side.
We already changed valve cover gasket both bank (all dry)
We changed all cam sensors position (4) (all dry)
We washed all the engine to see where is the source.
There is oil on the alternator (which i don't like) ......and there is oil around the power steering hose. We had to remove the internal wing cover plasti to see better but still...There is 3 hoses for power steering and from my understanding 2 are return and 1 for pressure....it's really jam pack in this area .....

From your experience what do think ?

Thanks a lot (engine is N62) with 70k miles...
