What happens if you don't change the cam phaser?

[Adopo]

My Ford dealer replaced the Cam Phasers (2nd time) in Oct under an Emissions warranty. As long as it was for free I'm fine with it.

emissions warrnaty was that something you purchased? Based on total milage?

You can check your PCM calibration level via Forscan. This is how it shows for my 2019 (I had to have it updated after the dealer changed Phasers. They don't update it automatically after changing Phasers):

Anyone know if you can get this calibration file from somewhere and then install it using Forscan?

Unfortunately not. Must be done with Ford IDS software and VCMII or VCMIII hardware. You could do it yourself if you wanna spend ~$1000 for the VCM and the IDS software license: https://www.motorcraftservice.com/

Thanks for the info. I guess after I do my cam phasers, I will need to give the dealer a call to see how much they will **** me to do the update.

No, I have an extended warranty, which was in force last month (expired now) but she said, Nope, we got this fixed under an Emission Warranty. Maybe its a CA thing?

I had them replaced at some point, but I will need to look it up. I have been told that they must have replaced the worn parts with
Regarding that recall, I had the cam phasers changed once, and I have been told they must not have used the updated parts? Could this be the case? Also, as a novice, what do you mean by the new calibration? That sounds like a setting, and not a part?

The old parts haven’t been available since 2019. So almost impossible that they used “old parts”, but that speculation continues to run rampant on social media of course.

Program 21B10 is a PCM calibration update; it’s entirely responsible for the operation of the engine and VCT system. The original calibration was causing problems phaser wear due to a combination of duty cycle and oil pressure at hot idle. The new calibration corrects both of those issues.

Have your wife call Ford corporate and have her start crying. Maybe they will cover it or discount it. Worth a shot!
