Oil flow

That tube is supposed to hook to the air cleaner. Other option would be to replace it with a closed breather cap.

oil comes out of the tube? please explain. first of all, the cars were either open emissions or closed emissions. closed is like what yours sounds like it was supposed to be. the cap pulls fresh air into the crankcase through the cap from the air cleaner and then the pcv sucks air and crankcase vapors out of the engine and sends them into the combustion chamber. an open system simply lets the car draw air from the engine compartment basically. anyway, you should not have any oil coming out onto the ground. there are supposed to be baffles inside the valve covers that prevent oil from splashing out. also, have you changed your pcv valve lately?

If it's not hooked up to the air cleaner, I am not surprised that some oil would come out of it. I imagine it's not a lot though.

ya, even if you have the baffles in the valve covers and a breather cap, there is still oil residue around that cap.
