Fresh engine, wiped cam? Tick? (new pics added)

You have to figure, the pushrod cup is what is moving (rattling), it's free to travel, because there is no spring behind the cup. The only thing that holds the cup in place is the clip, so there is some travel between the plunger and the clip. I did leave the lifter sit in oil overnight and I tried to pump it up this morning. Still no pressure, other then spring tension. Like I said earlier... before I took these apart I couldn't move the plunger at all, whether that was because it was stuck, or it held oil pressure at that time, i don't know.
