The part you're talking about only comes from Ford with the plastic tube (about $30).I just went to autozone and bought a new pcv valve. The elbow is probably a dealer part, so I just put a regular vacuum line on. I know there is the problem that it will pinch off the airflow, but I needed a quick fix. My other hose was leaking. Hope this helps. Do a search on here for pcv valve, you will get a ton of information.
