My truck is a1952 3100 with 1950 doors. Langdon two carb set and Patrick’s 3:55 ring & pinion. Agree with you about the wipers. Question, should I use the Pcv system or stay with the draft tube.
That would depend on your driving habits and whether you are strict about oil change frequency.
Crankcase ventilation with a draft tube would be just fine if most of your trips involve going over 25-35 MPH. That is the speed at which crankcase fumes will be sucked out via the draft tube. Below that speed, not so much.
PCV would be better if you were a delivery driver in a city with lots of stops and starts with lots of idling, where you seldom go over 25 MPH, or if the only driving that you do is on and off of a trailer.
Crankcase ventilation is important for removing blow by fumes which will contaminate the oil which will wear out bearing surfaces and rings prematurely.
