before posting try searching....https://www.jk-forum.com/forums/show...l-sucking-3.8& this is a common occurrence and is considered acceptable by Chrysler. Many have switched to a different weight of oil to help with the problem.

I have also had this issue and called my dealer yesterday and they said that they had another JK come in and they replaced the PCV hose and that solved the problem.. I'm gonna let them try that on mine and see what that does..

What kind of oil are you using? For awhile I was using Royal Purple and was good to go. But then it started using more oil than I thought it should for a new rig. So I changed over to Mobil 1 and all is well.
