Another option is to just attach breather caps to where the PCV Valve is located. The drawbacks to this are that the filter in the breather can get clogged with oil, or leak onto the rest of the engine. Breather caps also require removal for inspection to make sure that they allow for easy airflow. The end that the PCV Valve hose connects into to, on the other end from the PCV Valve, would have to be capped off as well. Another draw back is when one runs the air conditioning and doesn’t have it set to “Max.” When not using the Max setting, air is drawn directly from the engine bay and forced into the cabin, where it will start to stink. I’m not sure if the heater option would have the same effect, but I am guessing that it would when set to draw in fresh air. Lastly, not having the metered air return back into the manifold would cause your “check engine” light to come on, or your computer to throw a code.
