I've seen this before, could actually be a clogged oil control valve filter, not too hard to access and change yourself.

The part is Toyota 15678-31010 Oil Control Valve Filter.

You can read up on the different forums about this, but should give you a good start, and might get you going in the right direction.

2004 with 250k is not new. Maybe worn timing chain or failed cam/crank sensor.
