Please tell me if this is correct.

So I am stumped. I have seen 2 different setups for what is running to and from my carburetor and I have no idea if I am set up correctly or not. I stopped driving this Dart almost 20 yrs ago and I really didn't have much to do with the engine back then. The valve cover has a pcv valve running into the 4bbl Holley Carburetor, too big for the slant 6, I know, but that's what it had when we bought it. On top of the Holley is an Edelbrock air filter with a port in the bottom with a hose running into a hose, running to a breather cap. Is this correct, or not. I have seen this engine set up with a breather cap with no hose connector and with the hose connector. Also, there was some oil in the air filter which leads me to believe that oil was being pulled from the valves through the pcv valve. Please look the image over and tell me what you think.Engine.jpg
