This problem is usually the result of worn rings but since you already did that, then check the passage that the PCV valve is connected to. It might be clogged, causing a restriction. If that isn't it, then drill a hole at least a quarter inch in size in the top of an old valve cover filler cap and install it. Drive the vehicle and see if things improve. If they do, then check to make sure that you have the correct PCV valve installed.
