Did you ask for that or are they just doing it now? That's interesting if it's the latter, since 2020 and prior were spec'd for 5W20
Seems most common at first oil change, though anything is possible as it is 'normal' I had it after first change when using the Motorcraft Semi synthetic. I changed it at 1K miles, then again at 5K. I added Ceratec to that change (Valvoline Synthetic 5W30) and havent had it since. Am at 20K, change oil every 5K
No typewriter tick but have the 2k rattle.
While I like the dual VVT of modern DOHC V-8 motors, I loath the VVT racket they cause. I wish there was a way to disable the cam phasers and lock in the cam profiles. Fuel mileage and maximum engine performance may suffer, but that infernal 2k-2.5K light/off throttle clatter drives me nuts.
The motor is a DOHC with Variable Valve Timing (VVT) on the intake and exhaust cams. The cam phasers (or whatever Ford Calls them) advance, and retard cam timing for max power and economy. It's mostly done by oil pressure determined by the ECU through some kind of Dearborn black magic (algorithm).
Thing is, not all Coyotes have a "2K rattle", or the "typewriter tick" ... so it's got to be related to how each individual engine ends up as a system - ie, parts variance and/or assembly variance during production.
