Yes PCV is the important check, but the snot up the dipstick can occur even when the PCV is good. I'm not talking about a lot of gases trying to escape like steam from the spout of a boiling kettle (that would suggest blocked PCV), more like the steam rising gently from a hot cuppa. The dipstick tube is quite long outside of the engine block so it never warms up hence the condensation especially in winter. I had it on mine when I bought it, changed the dipstick and the tube as the top of the stick was also broken and no problems since. The replacement dipstick now has two O rings rather than one.
