Look into doing a compression check on all cylinders. Blow-by is typically caused by worn rings and dry and wet compression checks will help determine if it is bad rings.

I think you are right in your assumption, but better to do the checks first. It could just be a bad PCV system, but smoke in the crank case (not just oil mist) is not a good sign.
