Hi Guys, I am trying to find a replacement for the PCV valve as it has rough idle and checking the PCV valve the diaphragm has a split in it, part number on current one is 06H129101B (Image attached) but I cannot seem to find a replacement anywhere, did an AI search and it suggested 06F129101N or 06F129101R but these look a bit different as they have an extra port at the end. Any help would be greatly appreciated.
