I bought the 9-5 1998 model (130.000 miles) 4 month ago, it had no PCV upgrade. So the root cause seems to be 130000miles missing PCV upgrade.
The first thing I did was to deliver the car to a Saab workshop for chains and gear replacement and PCV upgrade, the chain was rattling.
The mechanic said that under the valve cover it looked fine, no serious sludge found. I regret to say that I did not ask for a oil pan removal and cleaning so this was not done.
The first round of kerosene flush I did just for safety, to clean gunk (if any), but after the kerosene job the inside of the oil filter was like this:

As you see a lot of debris found.
Note: I only replace the filter every 14 days (no oil change), and only refill filter replacement oil loss ( ¾ liter).
I drive 500 miles a week, so it means filter replacement every 1000miles. Regular oil change (plus kerosene flush) I do every 6.000 miles.
I will continue to do this until I do not find the debris like this inside the filter housing:
