I’m not too knowledgeable on crankcase venting and seeking some advice. The S4 T2 I bought came with the current setup pictured below. It’s routed from the filler neck and the middle iron nipple to the vented catch can. Is this adequate or should I reroute it since it’s not hooked to a vacuum source?
