There is no oil trap or fire screen on a car. I did check just to make sure and there is no listing for either of them. The turbo model has an oil trap to return oil back to the pan but that is connected to the oil pump.
Now If oil is coming out of the valve cover that is either because of the pcv system being pluged or bad rings that are allowing to much pressure in the engine and it has to go somewhere. So I would check the PCV system and do a compression test and it should be 128 psi per cylinder. Get back to me with what you find.
