None of those possibilities is inexpensive. I don't know if the valve *seals* can be changed without pulling the head in a Saab. But, what you really need to do is a Compression test to find out which it is. After that, some analysis of the related components needs to be done. If your rings are bad, it sometimes means it's time to overhaul the engine (since you are doing 3/4 of the work already). If the valve seals (only) are leaking oil, a head job (or just seal replacement) can be much cheaper. Get a compression test done by someone who knows what they are doing, preferably a Saab mechanic (independent or dealer). Get an estimate at places you can have it fixed. That's all that really counts.
