1st photo , you can see both oil slots , the back slot is the one that is "uncovered" when using the Nutter adaptor.
The pre eagle 1st cam journal is feed from the bottom, the VVTs are fed from the top.
2nd photo, oil comes up from the bottom, comes out this passage, travels around the channel( keep in mind there is plate that covers these channels) goes up into the solenoid then feeds the journal.
The plunger in Nutters kit is supposed to block off oil to the 2nd slot ,but I filled that with epoxy anyway.
