Guys,

I'm happy to report that I have my car back, and the clicking is gone. Here is the information on the service report...I hope it helps everyone out:

Job #1

Cause: NOISE FROM ENGINE, POSSIBLE LIFTERS
Correction: START VEHICLE NUMEROUS TIMES. ALL OK. ROAD TEST VEHICLE. NOISE WAS HEARD. PERFORM BRIEF TEST. NO FAULTS REGISTERED. PERFORM SMOOTH RUNNING TEST. ALL OK. CUT OUT INJECTORS ONE BY ONE. NOISE CHANGES WHEN INJECTOR ON CYLINDER THREE WAS SHUT DOWN. SUBMIT PUMA CASE. RESPONSE IS TO REMOVE VALVE COVER AND CHECK LIFTERS

Job #2 and #3 unrelated

QTY 1 11-12-7-531-224 BEAR. LEDGE
QTY 15 11-12-7-535-024 BOLT


Alright, now for the meeting with the service manager. They did flush out the engine, but I will be hitting the oil with a Blackstone test in a few thousand clicks to see how things are. Given that there are so many of us with this problem, I wanted to make sure that this has made it into the BMW-NA database, and he assures me that it has. (I guess that's what Puma means)

His theory is that things happened in this order: cam and housing not in tolerance from factory causing oil starvation to cam and bearing, and the subsequent scoring...then the noise came as a result of that

He has also all but guaranteed that the problem will not come back. I'll let you know in about 13000 kms...
