CC doesnt catch anymore , is the ventilation valve is stuck closed?

My CC doesnt catch anymore , is the ventilation valve is stuck closed? I noticed a small increase in oil consumption and the catch can is no longer pulling anything out of the engine. I am wondering the symptoms are related? Perhaps the crankcase ventilation valve is stuck closed, pressurizing the crankcase causing oil blow by.

Are you getting a CEL ? Maybe the PCV is stuck which should throw a CEL.

Weird,

Is you valve cover leaking any oil in the center ? Right near those spark plugs, did you take it of and look at the underside?
