That's a pretty wear intensive interface at the cam/lifter and it may be related to
some other oiling issue that is exacerbated(and fixed) by the oil pump tolerances. I don't know more than that, but I guess I should look into it a bit. Sweet, more work for me!

97K miles
Sound started around 95K miles but got a lot louder in the past week after adding MMO (not blaming on that - it probably just sped up the inevitable).
I change oil every 3K miles using mobil synthetic 5w30. I tried using 10w40 today (to see if it helped) but no luck. I was planning on having the oil analyzed this oil change, but added the MMO so I will wait until next time (I have the test kit already). It seems like this is not a common problem, but it's my luck. I've been meticulous with all maintenance btw in the 3 1/2 years I've owned the car, as was the one owner before me (have all of his records).

I found this post regarding the oil pump
It seems to be in an easily accessible location which is very good.<ul><li><a href="https://forums.audiworld.com/s4/msgs/1759332.phtml">Oil Pump</a></li></ul>

Only job for me that hasn't been DIY is timing belt.
Seemed a bit too much for me, especially because any problem could result in a lost engine.
I think the engine isn't receiving proper amounts of oil.

Not entirely... oil-flow usually goes from the crank to the valvetrain...
It may have enough pressure to lube the crank but not enough to push it's way up to the valvetrain :/
