 I finally noticed an oil pressure sensor down there... 24mm socket just
barely gets the thing on or off.

 Interestingly, there appears to be nothing wrong with the sensor that I
 took off the engine. But changing the sensor repaired the leak. >>

FYI--

You diesel and TD folks, this same sender (on top of the oil filter housing)
has split/leaked three times on me in 145k. Most recently on Friday. Put an
extra sender in your glub-compartment, along with a deep 24mm socket. ;)
