pressure plate experts

Well, let's discuss the "pop" you are hearing. As I understand from post 1 you hear this when the clutch plate releases the disc, as in peddle depressed. You/they heard no "pop" at the clutch shop? Does it happen when rotating or even with engine off? With the peddle depressed, can you determine maximum plate departure with a feeler gauge (.060" is a starting point per MP)?
Can you determine whether or not the release bearing contacts all three fingers at the same time while pushing the clutch fork rearward by hand?
