2021 Expedition Max XLT - Rattle (normal or Cam Phasers?)

[weezy_jw]

Hi all, we just bought a new to us Max XLT. It has 42k miles on it. I didn’t notice it at the dealership Friday, but this morning on a cold start a noticed it rattled for a few seconds. Is there a normal rattle on every start up vs the cam phaser issues? Or if there’s a rattle at all It’s the cam phasers? Thanks!

Cam Phasers. Generally audible for a few seconds on a a overnite cold start. Warranty time for a repair. Try to record it on first start in AM.

Also check your turbo wastgate. There’s a spring fix somewhere in this forum.
