This sounds like too much oil pressure and a failed
filter gasket. (Could be based on gasket creep due to
the cool weather and warming motor.)

Couple of thoughts: 

There is a oil bypass valve down in the oil pump,
right? (Isn't there also some sort of oil related
valve up in the head as well?) Perhaps one of these is
sticking. 

Is it possible you have the motor equivalent of
clogged arteries? Those passageways in the head (and
around the crank for that matter) can get gummed up
from old motor, new detergent in new oil flush
syndrome.

I kind of like the crack the sensor fitting and burp
the system idea although I have no direct experience
with that exactly to back it up.

When the motor has sat for awhile, what is the
dipstick reading right now?
