First off: Merry Christmas everyone. Family, friends, happiness, old cars. Too good.

But, just wondering, when you disassemble the PCV valve for inspection, is it normal for there to be a little oil at the base, maybe by quantity about 5 drops?

My diaphragm is new and hoses all connected properly.
 
If you've ever opened the oil fill cap on a valve cover after a good drive, you may have seen a cloudy vapor kind of wafting around inside the valve cover...there are microscopic droplets of oil in that vapor cloud.. That's the very thing that gets sucked into the PCV valve by the intake manifold, so yeah, there is going to be oil involved. You've just noticed it in a condensed form after the vapor cooled.
 
Totally normal. The PCV is ventilating oil laden ring bypass gases. The oil condenses as the gas goes through the cooler hoses and PCV valve. That is all the oil that would be spitting out the road tube into the atmosphere before PCV was mandated.

Happy New year too!
