GeoffInCarlsbad is on a distinguished road
Default Road Draft v. PCV

My '61 390FE has a Road Draft Tube, and I assume this is in place instead of a more traditional PCV for this 390FE.

It seems the only serviceable part is replacing the oil filler cap, where the filter in its intake is very, very dirty. The Shop Manual talks about both, but...it's not clear to me.

I am seeing smoke from the Road Draft Tube at when idling hot. I cannot judge if its excessive or not, because I don't know what it the norm.

If I replace the oil filler cap with a clean one, does that help? Also, should I consider a conversion to PCV? If so, how difficult and expensive is that? Is there really any reason to do a conversion?
