Thanks Dave. No affect on dipstick readings, which I check frequently. Any chance this could be insufficient crankcase ventilation?

ETA: I might be able to test this by cleaning the intake runners, adding oil to the crankcase, and using the oil pump primer to circulate oil throughout the engine. If the runners are oily again, I think this would be a good indicator that they're is an issue with the valve stem seals. Works in theory I guess.
