When I took the bellhousing off I noticed that the cam gear was chewed up along the top edge of the teeth. The crank gear showed no signs of damage. This wasn't normal wear - it was gouged. I assumed that something in the oil got sucked up into the meshing of the gears and gouged the aluminum cam gear. Not sure you can see the damage, but here goes:
Note to self (and everyone else): Follow the torque guidelines in the shop manual !!

I also had a deep score line in one of the main bearings (but no issue with the main bearing journal):
So, obviously there was some contamination in the oil but I didn't notice anything when I pulled the oil pan off. However, when I went to remove the oil pickup (an OTTO part) I discovered this:
You can also see a hairline crack across the top where the rest of the pickup support bolt hole could break off at any time. I'm guessing the guy who installed this stuff over-torqued the bolt and caused stress fractures in the aluminum case. At some time after the engine was reassembled it broke loose. The big piece fell into the pan but little stuff ended up in my gears and bearings.Cam gear damage...

Re: Cam gear damage...
Interesting. Damage on the top of the teeth is indeed unusual. I wonder if there was contact with an oil pan somewhere along the way.
