OK, here's a new question, I measured the OD of the existing hoses and they were 5/8" so I assumed the ID was 3/8" and that's what I bought. I noticed in the pictures above that you used 5/8" ID hose. Any real advantage to a larger hose here? Theoretically you would get more air flow, but isn't the PCV a sometimes open thing anyhow?
