I am not so good in writing or explaining this in english but i try.
Your pcv valve should be connected to the manifold or just below your carburator.
On the other hand you need a breather cap on the other valve cover connected or not to the airfilter.Filtered air gets through the breather oilcap in the engine and travels through the engine to the other side where it gets through the pcv valve in the combustion chamber.Why ? Some fuel particals find their way beside the piston to the carter , when you have bad ignition or bad entilation , our oillevel will rise and your engine will be lubricated with a mixcure of fuel and oil.
Hope you nderstand what am talking about.
