That's a Packard exclusive meant to allow checking the oil without carrying dirty rags in your expensive Packard.

Before the sight glass they used leveling taps operated by a lever reachable without getting dirty.

Just drain and refill the oil by the quart and check the gauge.

The drain plugs need only be 10 or so ftlbs of torque and over tightening creates big problems.

The gauge is easily repaired if it doesn't work.

Oil gauges were a common feature, but only Packard used the fancy watch crystal type.
