after checking online i saw a lot of people state a common fault for an air leak was the PCV. I had this swapped as the old one the orange rubber was split. the car was running smooth for about a week and problem came back.
Could the PCV have split again?
If i pry the top of the PCV open is it easy to put back together? Had someone else do it for me last time but isn't availiable and dont really want to go garage for it.
Thanks in advance
