Hello, I'm currently going through a similar process with SB100 for a car (SPF cobra) previously registered in another state. I need to close my breather....I have the PCV on one side, and
oil filler cap /breather on the other valve cover. Where did you find the breather that includes a hose but no additional PCV? I can't seem to find one that fits a 1 1/4 inch tube. Thank you! Dan
