Just an update. I used some brass fittings making a bit more baffling and some of the silver pot scrub pad wire to add some extra baffling inside the brass fittings and under the gasket on the aluminum flat valley pan. Now I think I am not sucking oil through the pcv valve any more, low end or any load seems much better, crisper and I’m hearing the carb air much more. I went with the autozone pcv1226DL for now, I also have the butler pcv for the flat aluminum valley pan. We will see, I’m trying not to have to have a vaccum pump, it is w72 modified, i may not of posted in the right place but it may help someone.
