Update from dealer
So, I just talked to the dealer. He sent me a schematic of the chain gear that shows the different drive wheels, chains and valves and pointed out where the chains have timing marks. He said the technician has verified visually by observing the marks as the chains move that the timing is off, so it is definitely not a problem with the sensors. He said sometimes the oil pump, which is driven by one of the gears, can seize and cause the chain to "skip" or can break a tooth on the gear. But, he said the oil pump looks fine. He also said the chains look fine -- they move with the engine smoothly as you would expect.
He is still not sure what it might be, but he thinks the next step is to drop the engine to see if a gear is broken or lost a tooth or something. He also said the variocam, which he explained adjusted the timing with load, might also be broken.
What do you guys think?
I should add that the dealer has taken these extra steps for me at no cost. So it's hard for me to complain that they are running up the diagnostic bill.
But they are not going to drop the engine for free. So I seem to be at a decision point.
