I like to use the last design of the filler tube as I think it performs the best. Ford realized that blow by was an issue and tried to correct it by changing the way the baffles are oriented in the tube but they never quite got it right. The interesting thing is that some engines have this problem really bad, others maybe a little, and some are completely blow by free. Probably due to the way oiling was experimented with in the block castings. Some designs better than others.
