Does your 2017+ F150 have the on/off throttle rattle and what are you going to do?

Ambitious But Rubbish
My 2018 5.0 does this and it's very noticeable in parking lots. Need to get in to see the dealer and see what they say. I will be bringing video with me.

I believe Cloyes also makes front end engine parts for Ford/

I modified the calibration to fix the noise. My truck is tuned and has been for a while, but either way, this sounds almost like a characteristic noise for this VCT system, but it can be alleviated greatly by modifying the calibration. I know no one or almost no one is going to be willing to do that, so chalk it up to this explanation.
The amount of cam movement when going on and off the throttle is an emissions and fuel economy thing. That's why it moves so much. Going from a very very low overlap scenario at light throttle when cruising to a larger overlap scenario in decel.

Wondering if maybe specifying which engine this applies to would be useful. There's only 6 choices (more if you count the Raptor Ecoboost) in that time frame, with updated versions of two of them in there too...

PS Is your calibration fix harmful to the engine? Seems to me less rattling would be a good thing. would be good for Ford to consider the calibration fix.

First off, that is god awful.
Secondly, I don't know if this was meant to be an Eco thread.
I wanted to ask the guys that don't hear it in the cab, but can hear it when the hood is open...
Is it definitely the VCT or internal for sure?
I know my electronic coolant pump makes the exact same noise but it's faint. I would never hear it with the hood closed, but maybe some are just louder.
I took a video trying to find that off throttle pop, but ended up hearing that instead and I never knew it was making that sound.
I suppose I'm lucky, that I don't hear it.

My answer is to get a ESP because I plan on keeping my 2017 for awhile. There's no freaken way that noise can be a good thing regardless of Ford BS. If/when something breaks in the engine I don't want to eat it a few years down the road. I have the noise (it's fairly faint) but I can darn sure hear with on/off throttle response especially when the engine is cold. For now I'm cranking the stereo up because I've yet to read where a dealer has really fixed the problem. I really don't want them tearing into the engine unless there is a specfic TSB from Ford on how to fix the problem. If this is best Ford can offer sadly this will be my last Ford product.....

Mine has had it since mile 1 and we now have 14,000 miles. Very noticeable in company parking garage only on cold start drive out. Had the TSB performed in late December that updates the ECU. Trans does shift much nicer, but the on/off throttle rattle seems unaffected. I'm trying to train my self to release the throttle much slower as I round curves in the garage. If you are careful you can completely avoid the noise, I know it's not a fix. I thought I read somewhere there was a variable runner-type mechanism in the intake manifold that was swiftly adjusting itself in this on/off throttle phase. That seems more plausible than the timing chain concern some mention. The conditions and sound are so precisely consistent... seems timing chain noise would not be so consistent. Just an opinion.
