Bruce has been nice enough to point out the merits of a PCV many times on this forum and the HAMB. If I have it correct, the military flatheads had them and the biggest benefit of having one is burning off the moisture in the oil and that keeps sludge from forming. I have one on my 8BA from the gent who sells the neat kit to do this on E-bay. Right now I have a Southwind heater vacuum plate under my carb that provides the suction. However, my plan is to run the tube from the PCV to the air cleaner and vent the crank case that way. I think that will allow me to keep my manifold vacuum higher and use it for the distributor vacuum source.
