Timing chain r&r

[Jleecare]

Yes, I saw that video before I start the process. I did check both side thru that hole make sure both sides lineup perfectly before I bolt everything up. Somehow I am still off a little to the bank 2 (driver side). My bank 1 code when away after the process. Can I just adjust the vanos on bank 2 only which out touching the bank 1 side? Or do I have to open up both sides again to get it retiming? It took me over 30+ hours to get it completed. It's a pain to go thru the whole thing again. Is there a way to tell if the code go away after the retiming before putting all the parts together? Thanks
