Gonna do some more driving, but apparently this was the main problem...

What was causing the tapping?

Not sure. The tapping has since disappeared.
The whole thing is still a little fishy so I'm going to be keeping a close eye on things.

Running well enough though. Floored it this morning through traffic and the car got up and went.

If it was running rich because of the O2 sensor, it could conceivably make the valves tap, right? (Because there would be too much fuel mixture behind them for them to close.)

I reckon so. Still seems odd.
