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

Some trucks didn’t have a cold start rattle but could exhibit a knock noise at hot idle; the calibration corrects that issue. Which is the reason the reprogramming should have been done first.

Not really. The general public spends far too much time and effort speculating about things via the internet instead of just following the manufacturer’s direction.

The recall was straightforward. Receive letter, schedule appointment, have the update done, and you get the extended coverage.

Yea i feel ya. That makes sense on the hot idle. Some of us have had bad luck with Manufacturer programs in the past. Many that dont work, ie freezing door locks. I cant get calibration engineers to completely agree with all of this either, so everyone still seems to have their own opinion. Calibration 101 answer, software can only do so much to solve long term durability issues if the hardware isnt up to the duty cycle.

So I had my PCM updated today at the dealer. When I scan now with forscan, it doesnt show that the strategy has changed.

@FordTechOne , Do I have to do anything special with Forscan to make sure its pulling the latest data from the PCM after connection?

Well, I had to force it to create a new profile. Maybe forscan doesn't update each module revision each time you connect. Weird.

problem solved.

For what its worth, i had 100k on my 2017 had no issues but a very slight tick, Had the ford dealer do the cam phaser recall and the motor blew 45 miles later, from what i could tell they did not get the cam phaser timing correct the motor was scorched black from heat when torn down
Ford replaced the motor with a new long block, ( i had the extended warranty on it) if not iam not sure how that would have gone.
