Depending on which of the collector drains its coming from it could be many sources..
I just completed the factory course at GE on the CFM-56-3 motor and one problem the instructor informed us about was a leak that came from the starter pad drain tube but when the seal was replaced or starter pulled, there was no evidence of leakage.
But what many in the field didn't know is the accessory pad above (going from memory here and I'm getting a little long in the tooth so bear with me) the starter actually has a small drain port that bleeds into the starters drain and both use the same tube.
So it would appear that its the starter pad leaking.. You pull the starter and no oil in the sump area. But oil still leaking from that tube. One of those things that make you go "Hmmmmm"
Anyway maybe a long shot but something to check out. I'll consult my CD's and notes from the class and report back later.
