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

I humbly and respectfully disagree. To my non engineering eye that locking pin and exposed spring of the 2017-2019 phaser looks like a 1890’s steam punk design and that locking pin is a shit design too. Theres a reason 2021 and up 3.5’s have no issues. To me this is a cut and dry case of a ****** part. It costs zero dollars to demand the MLz phaser .

i think theres an new oil passage in the new parts that keep the pin from binding on one side..

You’re not analyzing a part from a YouTube video, especially from an “engineering” perspective :facepalm:

I don’t know how many times I need to reiterate this before people stop coming up with their own “theories” that don’t align with the facts. Especially when your video claims they’ll “put back in the old part” that hasn’t been available for half a decade now.

The revised part (HL3Z-CD) still had the same exterior appearance, because that was never part of the issue. The issue was cutoff on 11/30/19, not in “2021”. The same phaser supplier/design has been used on 2.7/3.0 since 2015 and did not have issues.

If you actually compared the HL3Z-CD and ML3Z-A, you’d see that the spring is no different. It just has a thin piece of metal covering it from the front, which was due to the supplier change.

Hi FordTechOne,
Is there any benefit to have this PCM calibration update if the original cam phasers are in in the engine or does it only benefit the engine if the cam phasers have been updated?
Thanks,
Antonio
That’s literally the entire point. Without the new calibration the phasers will wear abnormally and eventually fail, regardless of what part number is installed.

Thank you. So maybe if I am not having the problem yet, and this update hasn't been done to the PCM, getting it may help prolong the life of the cam phaser until new ones are installed?

Lol, of course the dealership won't even check whether my 2019 was re-calibrated when the recall was issued. What a load of ********. "If you want us to check that we have to charge you for it" because the recall isn't current? To read a ******* program, am I understanding this right?

So, I've had my Phasers done twice now, 2019 and just last month (a week before my extended warranty expired). Had to take it back in last week because the check engine and wrench lights were on and it felt like I was in "crawl home" mode.
Turned out they didn't quite tighten down the turbos correctly - so now (of course) I can trust their workmanship.

QUESTION: Can I expect that the PCM was re-calibrated? Or not?

If it's not on the invoice I'd expect that they didn't do it.

Not likely. The program expired in 2022; owners were provided one full year to get it done. It’s a customer pay update now.
