Have Jeep Questions? Ask a Jeep Repair Expert for Answers
Hello my name is***** am an ASE Master Technician and I am glad to help you out with your question.
I believe you are describing the pcv valve breather tube.
My parts department at the dealer could look this up but they are closed. I do not have access to the part number. Go into the dealer and talk to the parts department, they can pull up a picture of the emissions system and you can point to the line that you need.
Please reply to this if you need more help and we can continue this conversation at no extra charge. This does not have to be my only answer. If you are satisfied with my service, please rate at the top of the screen. Rating does not close out your question. Remember, sometimes it is difficult to completely diagnose your vehicle without being there, but I will try to give you the best answer I can. Hoping to be giving you 5 star service.
