Actually, looking at the cap told the story even better. This cap is about a month old. Dammit.

The good news is I'm not seeing much oil anywhere else. The front of the engine looks nice, the timing belt is dry (and some kind soul renewed the water pump while also putting day-glo marks on the pullys), the top of the motor only has oil from before I replaced the filler cap.
My questions: are there any "gotchas" to this job? It looks pretty straightforward in the Haynes book and in the motor itself, but as someone who got handed a water pump R&R on an old 760 V6 - as a joke, thanks ex-boss - I've learned never to trust the easy-looking jobs. (If you've never seen the water pump on those, they're right on the front of the motor, four 10mm bolts, couldn't be simpler - until you find the 24-inch pipe welded to the back that goes all the way to the back of the motor. It ended up being easier to take the intake manifold off)
Also, while I'm down in that part of the motor, does anyone have recommendations as to other things I ought to get around to?
