Unhappy Timing Belt Cam Sprocket Question

I am in the process of replacing the timing belt on my EJ20. When i removed the tensioner both driver side sprocket rotated/shifted clock wise (to the right) from the videos and threads i've read i would have expected the top to rotate left and the bottom to rotate right.

I know i can only move the driver side upper sprocket clockwise, but that means i will have to make a near full rotation to get it back in alignment.

Any ideas?

As long as the pistons are off deck it doesn't matter. But if you have to rotate the sprocket all the way around, then it is fine.

This just happened to me a few minutes ago. Wasn't expecting that to happen.

Had the same issue with my 05 sti. They make a special tool, i think AMS does but it very expensive. So i just used an adjustable cam holder to line them back up.

I just rotated it clockwise real slowly. I didn't feel any major resistance. Just started the car up and it idles perfect like it always has.
