1965 Dart, 225, Crankcase ventilation and exhaust pipe.

My dart has as other Dart's 2 tubes on the valve cover. One in front, one in the rear. The rear one is a kind of a rounded one, no hoses to it of any kind. Just sits there.
In front there is a different kind of cap, larger, and with a hose that goes to the tube in the side of the air cleaner. The carb. (Holley 1920), has a port on the bottom that is plugged with a rubber/plastic (read tupperware) cap.

So, from the shop manual it seems like it has had two systems. California, and anywhere else in the Milky Way (Galaxy). The "Milky Way" version seems to have only one hose to the valve cover, while the California version seems to have two hoses.

I used engine degreaser on the engine a couple of weeks ago, and now just after having the engine running a little in the driveway the valve cover is wet from oil fumes down from the front tube, where the hose goes to the air cleaner. Which will be no fun when I paint the engine.

Any suggestions ? I will not say it is a lot of blowby in the engine, but it is not vacuum either to put it that way.
