As I mentioned above, I have abandoned the factory PCV setup in favor of the road-draft tube. Yesterday I returned from a 500mi road trip with camper loaded. That's ~9,000 lbs gross. Oil consumption was nil, weather was 80ish F, oil temp about 210, water temp 180-200F. No odors and no apparent oil underneath from the breather.
Despite the success of the road-draft tube, I'd rather have the PCV working. Perhaps I can clean the oil/vapor separator can as I did with the road-draft tube a while back. But I still have to come up with a new PCV valve. The one I have has the part no. Phak1 showed in his post. It is apparently worn out. I have all the necessary fittings and hard line.
