The PCV Opens when vacuum is applied from the intake manifold, It is not opened by crankcase pressure.

In the bad old days before emmisions controls, crankcase vapor was released to the atmostsphere through a open breather in the valve cover. CARB/EPA

RED MX5, We are actually agreeing. Point being, before PCV systems, crankcase vapor was not positively evacuated. I've got a 340 small block Chrysler in the garage with a pair of breathers in both valve covers, no tubes, valves, or hoses used.

Kitwetzler, you are no the only person to report smoke on the track, caused by oil in the front breather. It seemes to be dependant on how many turns, and in what combination they are in to get this to occur. Since my car is not a track only car, I have not put a can/baffle in the front breather hose.

 

Seung, #2 is the proper way to do it. It will collect the oil in the can before sending the vapor back to the intake which is the whole purpose of running the catch can in the first place.

Probably because it hasn't ran in 4 years! I need to track down some original 273 valve covers instead of the aftermarket covers that are now on it. PCV systems are far superior than not. Before the old Cuda' is back on the road, It will have a PCV. It will also not have a carburetor, but that's a different project.

That said, I had a problem with the fresh air vent, not the PCV.
