Has anyone had this issue before? Looking through my logs, it appears to have started on May 10th last year after about 10ish runs at the dragstrip. So far, I've verified the solenoids are in spec and even swapped them, but the issue stays on bank 1. No codes and the wiring checks out. Next on my list is to replace the CCT. Assuming the CCT is bad or there is some sort of oil blockage that isn't allowing the CCT to retract enough to loosed the cam chain for full intake cam advance.
Just looking for suggestions before I actually replace the CCT. Notice in the second image the shape of the Bank 1 cam angle. There is a consistent drop around 4krpm and recovery to ~7 degrees in a lot of my logs.
