Main items for oil leaks in the valley.
1a) HPOP Itself (already covered.)
1b) Check the HPOP lines (possible O-ring failure.)
1c) HPOP Non-Serviceable plug (needs the non-serviceable plug fix!)
2) CCV Dog-house O-Rings. Rings could be swelled, and not properly sealing - allowing oil to drain down on to the cover and valley.
3a) Turbo Pedestal O-Rings
3b) Turbo EBPV actuator O-Rings (if you have one)
Did I miss anything that could be added to this list for oil in the top valley area?
Edit, didn't the IPR and/or ICP Sensors have O-rings?
