2005 FXT

Default Trying to solve P0021 code

I guess I’m looking for confirmation that I’m on the right track. 05 FXT. Has a brand new factory short block. I cleaned and properly resurfaced the heads which only had 130k on them. New oil cooler, everything cleaned meticulously on assembly. All oil screens removed. P0021 shows up, and then will clear on its own, only to reappear. I swapped OCV side to side, no change. Factory oil filter, running Rotella T6, oil change is fresh. When I pulled the AVCS gears apart for cleaning, I noted a fair bit of scoring, and recall one worse than the other, though don’t recall which one. I’ve reached the conclusion that I just need to replace the left AVCS gear. Everything is box stock, no mods. Car runs great, no rough idle or other driveability Issues. Did I miss anything?
