    Almost sounds like it's missing, so I would lean towards broken valve spring, followed by rod bearing, and perhaps (though unlikely) piston slap.

    Please keep us posted as you will obviously be going back to dealer. Good luck with it!!!!!!!!

    There have been some reports of broken valve springs in the 18 cars.

    That's what it sounds like. Get it to the shop. She don't sound healthy.

    I have 700 miles on mine and have been beating the piss out of it. Nothing like this yet for me, but could happen soon enough considering some of the reports ive seen of this issue.


    What is build date on your car?

    Dealers called today said they found the source of the noise and after they talked to ford being the intake runners inside manifold. I highly doubt that’s it. But well will see. The sever advisor said ford said they have had a few issues with the runners in the 18 manifold

    Interesting. Please keep us all updated, and if you can post a pic of the issue, that would be informative and appreciated.

    Good luck with the repair!
