Re: Opinion on PCV valve for flathead?
You need to pick a PCV valve made that is close to your engine displacement. I use one for a 1990 Plymouth Voyager 3.0L or 181cid, V6. The number is PCV333. I went smaller and this works well for me. No oil mist on firewall and didn’t affect my carbs. I have two 97s and 269cid on a 59A.
