So which was part “C” that I had installed ?
I suspect that they left the complete suffix off of the end of the part number when the repair order was written.

Do you know if 2020 units built in 10/2019 contain the updated timing parts? Also fan you shed some light on what appears to be the root cause on the locking pins starting to mess up? Oil viscosity? Mfg tolerance , supplier of metal not within grade , etc? I would like to learn more as there does not seem to be many tear downs and analysis of the specific failureI suspect that they left the complete suffix off of the end of the part number when the repair order was written.

Seems crazy they can’t fully resolve it. It appears to have been an issue since 09 with triton 5.4’s

Yes! mine was a 9/18 build so mine should be in the clear. It's been oh so quiet so far, this is great!!It's been resolved...I have not seen any vehicles after the build date cutoff exhibit the issue in question. This concern is completely unrelated to the 5.4 3V, which had early issues with the VCT system that were resolved with revised VCT solenoids. The most common Ford 3V issues occur on vehicles with higher mileage, and are directly attributed to a lack of maintenance and/or poor quality oil/filters. These engines are extremely sensitive to lubrication quality and filtration; any wear to the cam journals reduces oil pressure to the VCT phasers, causing the PCM to lose control of the timing. Every engine with I've serviced with this issue has scored journals and poor maintenance history. Cheap oil filters are one of the biggest culprits; the filter media breaks down, falls apart, and gets pumped through the oil galleries. When it reaches the heads, it scores the cam journals to the point that they bleed off oil pressure.
Yes. Build date cutoff was 10-Jul-2018. All vehicles after that build date have the updated parts and calibration. I cannot comment on the exact failure mode that caused the issue, as I am not a Ford Engineer. All I can tell you is that the phaser part number and PCM calibration were updated, and I have not seen any concerns on vehicles built after that date.
