Many thanks Luddite! This all started with my noticing that I'd have about 2-3 tablespoons of oil under the car about every 2 weeks. I tend to drive the car 4-5x per week for about 30-40 minute stints per day. This led to a dye check with the assumption that the front or rear main seals were the culprit. When both turned out OK and the dye isolated the source to the dipstick...I was a relieved and then drilled a hole through a small rubber cork, and pushed the dipstick through said cork...and that appear to have essentially cured the problem.
Thanks to the input from you and others, I feel fairly confident that the crankcase is venting sufficiently - and will probably just continue to drive and enjoy the car!
