Update:

Rubber glove on oil filler port test checks out OK; on warm engine, vacuum suction pulls glove inward, not outward pressure.

The car has been running Volvo OEM multi (three) ground spark plugs. Had a few issues with these plugs in the past including one plug blowing out entire center electrode in #2 cylinder, and now this latest episode. As an experiment, replaced #3 plug with a used NGK single ground strap copper plug (BKR6ES) I had kept as a spare. So far, so good over about 400 miles.

I'll add the leak down test to the To Do list.
