Also, a PCV system should be a closed system to be ideal. It sounds like your setup is open if you have a stock oil fill cap and you see smoke.

A PCV system will have a place for air to enter - such that the PCV can pull the fresh air through the engine. On a typical OHV setup there is a breather on one valve cover (air to enter) and the PCV pulls it across the engine to the other valve cover.
On a flathead ford - the system is obviously retro-fitted and I don't know where he has the 'incoming air side' of it nor the PCV valve. There should only be one intake side and the best situation is for it to be at the rear of the engine and make sure there is a baffle tube to direct it down into the crankcase. I'd weld up the front block vent tube (cap it) and put he PCV valve into the side of the tube (so it's hidden in the valley). Then I'd plumb my vacuum source under the manifold.
