So been driving around a month plus with the intake partially disconnected. I had it into the dealer last month and they found “nothing”. It was very loud above 3-4K rpm. Was fueling up and decided to look for a second time under the hood, pulled the oil fill cover and there it was! Fixed it on the spot. (Always carry basic tools I’m in the fire alar, biz) Just sent the dealer an email on what I found and repaired. Looks like it pulled loose when they changed the oil. I am at 19k so I’m in for an oil change every 2 months...putting on miles quick!
