Your post aligns with what my Indi said. The goo is emulsion of condensed water vapor - not unusual in cold climates. As some claim they never see it, perhaps they drive a manual or let's say in the higher rev range?

The OP indeed had a CCV fail when it started sucking oil. The goo would be a bugger to be greeted with after a system change out. I hoped the newer, enlarged dipstick may hold great magic? Probably not as the OP cleaned his with the same result.

Guess we'll drive'em like a stolen bicycle from now on!
