Typical VW flat four lifter thing. Type 4's do it too. When the cam is
left pressing against a lifter that has a valve pushed open, the valve
spring tension eventually pushes the oil out of the reservoir in the
lifter.

The cure? Drive it. Be a little easy on it, as one valve isn't opening
all the way. It will pump up in time, usually 15-20 minutes. If you are
too bashful to drive around the neighborhood with the Hillbilly-sounding
motor, rev it in the drive to about 2k or 3k for 15 minutes or so. It
will eventually refill once the oil is thin enough.
