To see if it's the rings do a compression check. If #6 is not lower than the other cylinders, it's just the valve stem seals. If it's got low compression, it's the rings. But it would be odd to just have one cylinder with bad rings. Valve stem seals are known to wear on the top end of these motors. I did mine at 122K when I did the head gasket replacement, just to be safe.

What a kick that would be. Doing that kind of work (heads or rings) would approach the price I'd get for the whole car. Wrong time for this to happen.
The seals? Big job? Means pulling the head, gasket re and re and all the rest. I think I'm answering my own question already.
Oh well...thanks for the advice. I'll run a compression test next.
